Begin with criminal-procedure doctrine
Identification procedure doctrine separates due process, counsel, evidentiary reliability, and trial-use questions. A showup is not automatically unconstitutional, and suggestiveness alone does not state every due-process predicate; government arrangement, necessity, misidentification risk, reliability circumstances, and remedy must be tested under current law. Sixth Amendment counsel doctrine depends on initiation of adversary proceedings and the type of critical stage. Photo procedures, live lineups, and in-court identifications must not be treated as identical.
Due-process and self-incrimination text
The Fifth Amendment supplies federal due-process and self-incrimination clauses relevant to identification procedure analysis. Verbatim constitutional text: “Amendment 5 No person shall be held to answer for a capital, or otherwise infamous crime, unless on a presentment or indictment of a Grand Jury, except in cases arising in the land or naval forces, or in the Militia, when in actual service in time of War or public danger; nor shall any person be subject for the same offence to be twice put in jeopardy of life or limb; nor shall be compelled in any criminal case to be a witness against himself, nor be deprived of life, liberty, or property, without due process of law; nor shall private property be taken for public use, without just compensation.” Source: U.S. Const. amend. 5; https://www.neochart.com/catalog/constitution/amendments/amendment_5/const_amend5_22b2c981e2b9/const_amend5_0001/index.html; data via neochart.com, snapshot 2026-08.
Counsel and confrontation text
The Sixth Amendment supplies counsel and confrontation protections, with attachment and critical-stage doctrine explained separately. Verbatim constitutional text: “Amendment 6 In all criminal prosecutions, the accused shall enjoy the right to a speedy and public trial, by an impartial jury of the State and district wherein the crime shall have been committed, which district shall have been previously ascertained by law, and to be informed of the nature and cause of the accusation; to be confronted with the witnesses against him; to have compulsory process for obtaining witnesses in his favor, and to have the Assistance of Counsel for his defence.” Source: U.S. Const. amend. 6; https://www.neochart.com/catalog/constitution/amendments/amendment_6/const_amend6_63200243ad3c/const_amend6_0001/index.html; data via neochart.com, snapshot 2026-08.
Pin the synthetic procedure record
A synthetic witness encounters a prompt showup, a later live lineup, and a separate image array. Administrator identity, instructions, fillers, sequence, witness words, confidence, recording, counsel, and prior exposure are populated.
Work the procedure application
The trace classifies each identification event, then separately tests government-arranged suggestiveness, necessity, reliability circumstances, and remedy. The live-lineup branch also checks whether adversary proceedings had begun and whether counsel doctrine applies. Confidence is recorded at the time and never converted into an accuracy score.
Read the populated procedure record
The identification record contains witness, suspect, event type, date, administrator, instructions, fillers, sequence, suggestive feature, necessity, reliability circumstances, confidence statement, recording, counsel attachment, presence or waiver, contamination, later identification, proposed use, remedy, and unresolved status. The record contains 13 populated rows.

Read the complete record
The complete record keeps sources, stated facts, and questions for review separate. Pinned sources: Verbatim snapshot or official authority. U.S. Const. amend. 5: Due-process and self-incrimination text. U.S. Const. amend. 6: Counsel and confrontation text. Synthetic record: Classroom events and fields only. Showup: Witness views one detained person near the scene shortly after an incident. Lineup: Later live lineup uses fillers with varying appearance; counsel and recording fields are disputed. Photo procedure: Administrator presents an image array with confidence statement, instructions, and sequence log. Procedure trace: Stage, legal test, evidence, remedy, and handoff. Procedure: Live lineup, showup, photo array, in-court identification, voice, fingerprint, or other identification method. Due process: Government arrangement, unnecessary suggestiveness, substantial likelihood of misidentification, reliability circumstances, remedy. Counsel: Adversary proceedings initiated, critical-stage doctrine, live procedure, counsel presence or valid waiver, remedy. Evidence quality: Blind or known administrator, filler selection, instructions, sequence, confidence in witness's own words, recording, contamination, prior exposure.
