Criminal Procedure Flashcards: What to Put on Them

Every card should have three parts on the back: a rule statement of twenty-five words or fewer, the operative limits or elements, and a parenthetical case name with a year. The front should be phrased the way the issue arises on an exam, not the way it appears in a table of contents.

A weak card reads: front, "Terry v. Ohio"; back, "stop and frisk." That tests recognition of a label you already know. A strong card reads: front, "An officer detains a pedestrian briefly. What quantum of suspicion is required, and what may the officer do to the person's clothing?" Back: "Reasonable suspicion — specific, articulable facts, judged on the totality of circumstances. A frisk requires separate reasonable suspicion that the person is armed and dangerous, and is limited to a pat-down of outer clothing for weapons (Terry, 1968)."

Do not put full Bluebook citations on cards. A case name and year is enough for recall; save citation precision for papers and briefs, where the format actually carries meaning. Volume and reporter numbers cost you review seconds and test nothing your professor grades.

Rule cards carry the load because criminal procedure exams reward correct sequencing of tests, not case recall. Reserve case cards for decisions that created or moved a rule, and where the facts are the rule.

Kyllo (thermal imager aimed at a home, device not in general public use), Jardines (drug dog on the front porch), Riley (cell phone seized incident to arrest), and Carpenter (seven days of cell-site location data) all belong on case cards with facts, because the holding is defined by the fact pattern. Illinois v. Gates belongs on a rule card — "totality of the circumstances for informant-based probable cause" — because nobody grades you on the anonymous letter.

Hypo cards are the ones students skip and shouldn't. Front: a three-sentence fact pattern. Back: the issue, the rule, the application, and the strongest counterargument. Draw these from your professor's hypotheticals and old exams, since those are the fact patterns your grader thinks are interesting.

Build one sequence card first, and review it more often than anything else. Front: "Fourth Amendment analysis, in order." Back: (1) government conduct; (2) search or seizure — Katz reasonable expectation of privacy or Jones physical trespass on a constitutionally protected area; (3) warrant supported by probable cause and particularity; (4) if no warrant, does a recognized exception apply; (5) does this defendant have standing (Rakas; Byrd for the unauthorized rental driver); (6) if there was a violation, does exclusion follow or does a doctrine cut it off.

Then make one card per warrant exception, and write the scope and timing limits on every one. That is where exams are decided. Search incident to arrest of a vehicle requires that the arrestee be unsecured and within reaching distance of the passenger compartment, or that there is reason to believe evidence of the offense of arrest is inside (Gant, 2009). A traffic stop may not be extended even briefly beyond the time needed to complete the mission absent independent reasonable suspicion (Rodriguez, 2015). Consent, automobile, plain view, exigency, inventory, and special needs each get the same treatment.

Give the exclusionary rule its own subdeck: good faith (Leon), independent source, inevitable discovery (Nix), and attenuation (Strieff), plus a card on what exclusion does not reach — grand jury proceedings, impeachment of the defendant's own testimony, and parole revocation in most jurisdictions.

Confessions doctrine is a series of triggers, so write trigger cards. Miranda applies only to custodial interrogation, so you need one card defining custody (would a reasonable person feel free to terminate the encounter and leave) and one defining interrogation (express questioning or its functional equivalent — words or actions police should know are reasonably likely to elicit an incriminating response, Innis).

Then card the invocation rules as a set, because students confuse them under time pressure. Invocation must be unambiguous, and silence alone is not invocation (Berghuis v. Thompkins). Invoking counsel bars further interrogation on any offense until counsel is present or the suspect reinitiates (Edwards), unless there has been a break in custody of at least fourteen days (Shatzer). Add cards for the public safety exception (Quarles), the undercover-agent exception (Perkins), and the Elstad/Seibert pair on second warned statements.

The Sixth Amendment right to counsel needs its own attachment card: it attaches at the initiation of adversary judicial proceedings (Rothgery), is offense-specific under a Blockburger test (Cobb), and is violated by deliberate elicitation (Massiah). Make one explicit comparison card listing the differences between Fifth and Sixth Amendment counsel rights side by side.

Whether you cover this depends on your school. Many schools split the subject into an investigation course (police practices, exclusionary rule) and an adjudication course sometimes called "Bail to Jail." Some professors cram both into one semester and cover charging, pleas, and trial rights in three weeks. Check your syllabus before building a deck around a bar-style outline.

The adjudicative material is unusually number-heavy, so make number cards: a probable cause determination after warrantless arrest is presumptively timely within 48 hours (McLaughlin, following Gerstein); Barker v. Wingo's four speedy trial factors; Strickland's two prongs; Brady's three elements; Batson's three steps; the Rule 11 plea colloquy requirements; and Ramos on jury unanimity in state criminal trials. Add Lafler and Frye for ineffective assistance during plea bargaining, which professors love because it collapses two doctrines.

Use minimal-pair cards. Front: "Two-step warned/unwarned interrogation — when is the second statement admissible?" Back: contrast Elstad (good faith, curative effect of warnings, admissible) against Seibert (deliberate question-first strategy designed to undermine Miranda, inadmissible), and list the factors distinguishing them. Do the same for Gant versus the general search-incident rule, and for Strieff versus Wong Sun.

Keep an error log and convert every wrong practice answer into a card within twenty-four hours. Write the card around why you got it wrong, not around the topic. If you missed that Whren makes an officer's subjective pretext irrelevant so long as there is objective probable cause for the traffic violation, the front should be a pretext fact pattern, not the phrase "pretextual stops."

Also card what your professor emphasized that the bar does not. If your course spends two weeks on policing and race, on state constitutional divergence (several states still apply an Aguilar-Spinelli-style informant test rather than Gates), or on critiques of the exclusionary rule's deterrence rationale, those need cards too. Open-book exams change the mix: fewer definition cards, far more trigger and issue-spotting cards, since you can look up the black letter but cannot look up what to look up.

Use AI to reformat material you already have, not to supply material you don't. Paste your own outline section and ask for question-and-answer pairs, request three minimal-pair comparisons from doctrines you specify, or ask it to generate fact patterns that turn on a rule you name. Those tasks are transformation, and the failure modes are visible.

Do not ask an AI to tell you what a case held, and do not let a card enter your deck unless you can trace it to your casebook, your professor's slides, or a supplement you trust. Language models confidently produce plausible-looking case names, invert holdings, and attribute real rules to the wrong decision — and criminal procedure is unusually vulnerable because the case names cluster (Miranda, Massiah, Montejo, Moran) and several rules have been partially overruled. Montejo overruled Michigan v. Jackson; a model that missed that will teach you a rule that no longer exists.

Build the deck as you go, one topic at a time, within a week of covering it. A 250-to-400-card deck reviewed daily from October beats a 900-card deck assembled in reading period, which you will not finish and will not trust.
