Abigail Alvarez faced a zoning citation carrying up to one year in jail for repeated passenger pickups in a restricted transit zone. The municipal court conducted a brief bench trial without offering her a jury or providing appointed counsel. Alvarez was convicted after the hearing. The conviction cannot stand because the Sixth Amendment right to assistance of counsel was denied in a criminal prosecution exposing her to imprisonment.
Antonio Alvarado was arrested and clearly told officers he wanted counsel before any further questioning. The next day a different detective visited him in jail and resumed interrogation about the same offense without providing an attorney. Alvarado made additional statements during that session. Those statements are inadmissible because police reinitiated questioning after the invocation of the right to counsel.
Alice Atkins was charged with falsifying energy rebate applications. Her appointed defender never interviewed technicians or obtained work-order logs showing others had access to the system. The jury convicted Atkins after a one-sided presentation of the state's evidence. The conviction is vulnerable because counsel's failure to investigate readily available exculpatory material undermined the adversarial process.
Adrian Aguilar was shown a single company photograph two days after a server-room intrusion. The witness identified Aguilar from that photo and later from a live lineup. Aguilar moved to suppress the identifications on Sixth Amendment grounds. The motion fails because photo identifications are not a critical stage requiring the presence of counsel.
Ava Adebayo insisted her lawyer present testimony she knew to be false at her theft trial. Counsel refused to elicit the perjured statements and informed the court of the ethical conflict. Adebayo was convicted after the jury heard only truthful evidence. The conviction stands because counsel's refusal to assist perjury does not violate the right to effective assistance.
Alan Ackerman was taken to a ranger station room and questioned for thirty minutes about suspected illegal dumping. Officers obtained incriminating statements without advising him of his rights. Ackerman moved to suppress the statements. The statements must be excluded because the custodial interrogation occurred without the warnings that protect the right to counsel.
The right attaches upon the initiation of formal adversary judicial proceedings such as indictment or arraignment. Once attached it extends to all critical stages of the prosecution where counsel's presence is necessary to protect the defendant's interests.

No. Photo arrays are not considered a critical stage requiring the presence of counsel under the Sixth Amendment. The procedure may still be challenged on due process grounds if it is unnecessarily suggestive.

Counsel must first attempt to dissuade the client from committing perjury. If unsuccessful counsel may refuse to present the false testimony and may disclose the perjury to the court as a remedial measure consistent with ethical rules.

Effective assistance is presumed unless counsel's specific errors so undermine the adversarial process that the trial cannot be relied upon to have produced a just result. Ineffective assistance claims ordinarily require a showing of particular deficient acts rather than general assertions about counsel's experience or preparation time.

Once a suspect in custody clearly invokes the right to counsel police must cease interrogation. They may not reinitiate questioning about any offense until counsel is provided or the suspect himself initiates further communication and validly waives the right.
