Search and Seizure Toolkit: Suppression Motions, Consent, and Warrant Challenges

Summary. A working kit: an exception matrix showing what the government must prove and where it fails; standing, burden, and timeline worksheets; motion templates for each theory; an officer cross-examination outline; the letters; a state constitution research plan; and the authorities.

SECTION A — THE EXCEPTION MATRIX

Exception	Government must prove	Where it usually fails	Key case
Consent	Voluntary under the totality; scope not exceeded; valid authority	Consent obtained during an unlawful detention; scope exceeded; coercion; third party lacked authority; present occupant objected	Schneckloth, 412 U.S. 218
Search incident to arrest	Lawful custodial arrest; contemporaneous; proper scope	Arrest unlawful; digital contents of a phone searched	Riley, 573 U.S. 373
Vehicle search incident to arrest	Arrestee unsecured and within reach, OR reasonable to believe the vehicle contains evidence of the offense of arrest	Arrestee handcuffed in the cruiser; offense of arrest has no physical evidence (suspended license, warrant)	Gant, 556 U.S. 332
Automobile exception	Probable cause the vehicle contains evidence or contraband	PC is conclusory; vehicle was within the curtilage of a home	Collins, 584 U.S. 586
Inventory	Impoundment lawful; conducted per standardized criteria; not pretextual	No written policy produced; policy not followed; scope exceeded an inventory	—
Plain view	Lawful vantage point; lawful access; incriminating character immediately apparent	Officer was not lawfully there; manipulation required to see it	—
Exigent circumstances	Hot pursuit, imminent destruction, escape, or emergency aid	Time to get a warrant existed; misdemeanor pursuit is not categorical; no home caretaking exception	Lange, 594 U.S. 295 · Caniglia, 593 U.S. 194
Police-created exigency	Police did not create it by violating or threatening to violate the Fourth Amendment	Entry threatened before the sounds relied on	Kentucky v. King, 563 U.S. 452
Terry stop and frisk	Reasonable suspicion; frisk requires separate armed-and-dangerous belief; scope limited to weapons	Hunch dressed as suspicion; frisk became an evidence search; stop extended past its mission	Terry, 392 U.S. 1 · Rodriguez, 575 U.S. 348
Probation/parole search	A valid search condition; reasonable suspicion (probation) or, for parolees in some states, none	No condition in the release document; scope exceeded	Griffin, 483 U.S. 868 · Knights, 534 U.S. 112 · Samson, 547 U.S. 843

SECTION B — WORKSHEETS

B-1. Standing and burden

1. WHOSE RIGHTS?
   Client's connection to the place/thing searched: ______________
   □ Resident   □ Overnight guest   □ Driver (owner)
   □ Driver (lawful possession, not on rental agreement) → Byrd: YES
   □ Passenger → may challenge THE STOP (Brendlin); trunk usually not
   □ Brief commercial visitor → generally NO
   □ Disclaimed ownership → generally NO
   Subjective expectation of privacy exhibited?  ________________
   Objectively reasonable?  ____________________________________
   ALTERNATIVE: trespass theory under Jones — was there a physical
   intrusion on a protected area to obtain information? __________

2. WAS THERE A WARRANT?   □ No → GOVERNMENT bears the burden
                          □ Yes → DEFENDANT bears the burden
   ← This is the first question in the file and it drives everything.

3. WHICH EXCEPTION IS THE GOVERNMENT RELYING ON?
   Identify it, then run Section A for what it must prove.

B-2. Encounter timeline (objective sources only)

Event	Source	Legal significance
Dispatch / initial observation	CAD	Basis for the stop
Stop initiated	CAD / video	Seizure begins
First contact	Body camera	Tier begins
Documents taken	Video	Mission underway
Records check complete	CAD / video
Documents returned / citation issued	Video	*← Rodriguez* trigger**
Consent requested	Video	Before or after the mission ended?
Consent given / refused	Video — exact words	Voluntariness
Dog deployed	Video	Extension?
Search begins	Video
Item found	Video / report
Arrest	Video

Build this from the CAD log and video timestamps, never from the narrative report. The single most productive question in the area is: what did the officer know at [time], excluding everything learned afterward?

SECTION C — MOTION TEMPLATES

C-1. Master structure

MOTION TO SUPPRESS

I.   INTRODUCTION — one paragraph: what was seized, and why it must go.

EXHIBITS: video (with timestamps cited) · CAD log · the warrant and
affidavit · agency policy · officer training records · photographs.

C-2. Unlawful stop

Argument. A traffic stop is a seizure requiring reasonable suspicion of a violation. Terry v. Ohio, 392 U.S. 1 (1968); Delaware v. Prouse, 440 U.S. 648 (1979). The officer's subjective motivation is irrelevant only if a violation actually occurred. Whren v. United States, 517 U.S. 806 (1996).

Here, the report alleges [violation]. The body-worn recording at [timestamp] shows [what it actually shows]. The State cannot rely on a violation the recording refutes, and the stop was therefore unsupported at its inception. All evidence obtained thereafter is fruit of the unlawful seizure. Wong Sun v. United States, 371 U.S. 471 (1963).

C-3. Unlawful extension (Rodriguez)

Argument. "A seizure justified only by a police-observed traffic violation becomes unlawful if it is prolonged beyond the time reasonably required to complete the mission of issuing a ticket." Rodriguez v. United States, 575 U.S. 348, 350–51 (2015). Authority for the seizure ends when tasks tied to the traffic infraction are, or reasonably should have been, completed.

The mission was complete at [time], when [the warning was issued / the documents were returned]. Everything thereafter required independent reasonable suspicion. At [time], the officer possessed only [list the facts as they existed at that instant]. Those facts — [nervousness / an air freshener / travel from a "source" city / criminal history] — are consistent with innocent behavior and do not amount to particularized suspicion.

C-4. Invalid consent

Argument. Consent must be voluntary under the totality of the circumstances, and the government bears the burden. Schneckloth v. Bustamonte, 412 U.S. 218 (1973).

Select the applicable grounds:

Product of an unlawful seizure. Consent given during an unlawfully extended stop is tainted, and the government must show attenuation.

Coercion. [Number of officers] were present, weapons were [displayed / positioned], the encounter had lasted [duration], and the client's documents had not been returned. A reasonable person would not have felt free to refuse.

Scope exceeded. Consent was given to [look in the trunk]. Officers [removed a door panel / disassembled the console]. Consent extends only as far as a reasonable person would have understood it.

Withdrawal. At [timestamp] the client said [words]. Any consent was withdrawn as to anything not already found.

Third-party authority. [Name] lacked common authority over [the place]. Alternatively, the client was physically present and expressly objected, which controls as to him.

C-5. Vehicle search after Gant

Argument. A vehicle search incident to arrest is lawful only if the arrestee is unsecured and within reaching distance of the passenger compartment, or it is reasonable to believe the vehicle contains evidence of the offense of arrest. Arizona v. Gant, 556 U.S. 332, 351 (2009).

Neither prong is satisfied. The client was handcuffed and secured in the patrol vehicle at [timestamp], [distance] from the car, before the search began at [timestamp]. And the offense of arrest — [driving on a suspended license / an outstanding warrant] — is one for which no physical evidence could be found in the vehicle.

[If the automobile exception is invoked in the alternative:] The State must establish probable cause, and where the vehicle was parked within the curtilage of a residence, the exception supplies no authority for the entry required to reach it. Collins v. Virginia, 584 U.S. 586 (2018).

C-6. Device search after Riley

Argument. "Our answer to the question of what police must do before searching a cell phone seized incident to an arrest is accordingly simple — get a warrant." Riley v. California, 573 U.S. 373, 403 (2014).

Officers seized the client's phone at [timestamp] and searched its contents at [timestamp] without a warrant. The seizure was permissible; the search was not. All content obtained, and all evidence derived from it, must be suppressed.

[Where a warrant issued:] The warrant lacked particularity — it authorized a search of "the phone" without limitation as to categories of data, time period, or offense, and thereby authorized a general exploratory rummaging through "the privacies of life."

C-7. Curtilage (Jardines)

Argument. The area immediately surrounding and associated with the home is curtilage, "part of the home itself for Fourth Amendment purposes." The implied license permitting a visitor to approach the front door and knock does not extend to [bringing a trained detection dog / entering a fenced yard / walking to a side window] to gather evidence. Florida v. Jardines, 569 U.S. 1 (2013).

Here, officers [describe the intrusion], which was a physical intrusion on constitutionally protected property for the purpose of obtaining information — a search under United States v. Jones, 565 U.S. 400 (2012). No exception applies, and the observations made there must be excised from the warrant affidavit (Section C-8).

C-8. Franks challenge and excision

I.   THE SUBSTANTIAL PRELIMINARY SHOWING
     Statement in the affidavit: "________________________________"
     The truth: _____________________________________________
     Evidence: [record / video / witness declaration / document]
     The affiant knew or recklessly disregarded this because: ______

II.  MATERIAL OMISSIONS
     Omitted fact: _________________________________________
     Why it was material: __________________________________
     Affiant's knowledge of it: ____________________________

III. EXCISION ANALYSIS
     Affidavit ¶¶ ___, ___, ___ are stricken as false, reckless, or
     obtained through an unlawful search.
     What remains:
       ¶ ___ : ____________________________________________
       ¶ ___ : ____________________________________________
     Does the remainder establish probable cause?  □ No — the warrant
     is void and the search unlawful.  □ Marginal — hearing required.

IV.  RELIEF
     An evidentiary hearing under Franks, suppression of all evidence
     obtained under the warrant, and suppression of all fruits.

C-9. Response to good faith

Anticipating the good-faith argument. Good faith does not apply where (1) the affidavit is "so lacking in indicia of probable cause as to render official belief in its existence entirely unreasonable"; (2) the magistrate wholly abandoned a neutral and detached role; (3) the warrant is facially deficient in particularity; or (4) the affiant misled the magistrate with knowing or reckless falsehoods.

Herring v. United States, 555 U.S. 135 (2009), requires conduct that is "deliberate, reckless, or grossly negligent," or "recurring or systemic negligence." Here, [describe]. And where the underlying stop was unlawful, good faith reliance on a subsequently obtained warrant does not cure the original illegality.

Attenuation. Utah v. Strieff, 579 U.S. 232 (2016), turned on the discovery of a valid pre-existing warrant and on the absence of flagrant misconduct. Here [the conduct was purposeful / this stop reflected a routine suspicionless practice, as shown by [evidence]].

DEMAND TO PRESERVE EVIDENCE — [Name], incident of [date], [location]

Demand is made that your agency preserve and not overwrite, delete, or degrade: all body-worn camera recordings from every officer present, for the entire encounter including pre-stop, transport, and booking, in native format with metadata; all in-car recordings including any pre-event buffer; all station and booking video and audio; the CAD dispatch log and radio traffic; all notes, worksheets, and inventory records; and any photographs or measurements taken.

Retention cycles are short and this notice is given promptly. Failure to preserve after notice may support suppression, a spoliation instruction, or dismissal. Please confirm in writing that a litigation hold has been placed.

E-2. Public records request for footage

Pursuant to [state public records act], I request: (1) all body-worn and in-car camera recordings depicting me, [name], on [date] at approximately [time] at [location]; (2) the CAD log and radio traffic for that incident; and (3) the agency's current policies on stops, consent searches, inventory searches, and body-worn camera activation and retention.

I am the individual depicted in the recordings and request them under [the provision permitting release to the subject]. If any portion is withheld, please identify the exemption claimed for each withheld item and provide all reasonably segregable portions. Please advise of any fee exceeding $____ before incurring it. The statute requires a response within [__] days.

Claimant asserts the innocent owner defense and all other available defenses, and requests a prompt post-seizure hearing.

Filed within the [__]-day period stated in the notice dated [date].

SECTION F — STATE CONSTITUTION RESEARCH PLAN

Research the STATE ground FIRST. A ruling on adequate and independent
state grounds is not reviewable by the U.S. Supreme Court, and in a
meaningful number of states the state ground is the only one that wins.

□ Does this state have a GOOD FAITH exception?  (A significant
  minority reject it entirely.)
□ Does this state require an advisement of the right to refuse
  consent at a traffic stop?  Does it restrict consent requests
  absent reasonable suspicion?
□ Has this state rejected the THIRD-PARTY DOCTRINE for bank,
  telephone, or utility records?
□ Does this state protect curbside GARBAGE?
□ Does this state follow the federal AUTOMOBILE EXCEPTION, or require
  a warrant where the vehicle is secured?
□ Has this state rejected WHREN and made pretext relevant?
□ How does this state treat INVENTORY policy deviations?
□ AERIAL / technological surveillance?
□ ABANDONED property?
□ What is the standard for a state FRANKS analogue?

Cite the state provision by article and section, plead it separately,
and argue it first.
