6th Amd right to counsel: Offense-specific --> triggered by initiation of formal adversarial process (formal charges, indictment, arraignment, guilty pleas and sentencing, or preliminary hearing to determine PC to prosecute) and carries to all critical stages (deliberate elicitation of statements, physical post-charge lineup, and felony trial) of adversarial process. No right for: blood sampling, pre-charge lineups, photo IDs, preliminary hearings to determine PC to detain, post-conviction proceedings. Trial: automatically reverse conviction. Non-trial proceedings: harmless error test (gov can show beyond reas doubt that conviction would have resulted even w/o the improper E).
Any statement obtained by police from D related to crime (6th amd is OFFENSE-SPECIFIC) he is formally charged w/ is inadmissible in prosecutions case-in-chief (but can use to impeach if the statement was made during a non-trial proceeding) unless
he executed a knowing and intelligent/voluntary waiver -- but D does not have to specifically invoke 6th in order for it to apply; it is self-executing. D must have a rational and factual understanding of the proceeding and be competent.

Confidential jail informant after D invokes 5th and 6th rights: ok in terms of Miranda (no cop interrogation) but NOT for 6th --> per se right to not be questioned by an agent w/o presence of counsel after invoking this right (but it would be ok if it were about a different crime for which D has not invoked 6th)
