Legal Ethics Hypothetical
Driver and Shooter come back to Client's house, Shooter has a gun. Shooter fires a couple shots at Client's house. The shots miss Client, but one shot strikes and kills Client's brother. There are no other witnesses.
Shooter is charged with Murder 1, Driver is charged with accessory after the fact (he was driving) and Client is picked up on outstanding warrants.
You represent Client on the outstanding warrant cases. The DA wants to talk with Client about the Murder. Client is OK with that and you attend the meeting with him. You and the DA find out that [generally, a) Driver is very strongly inculpated in the Murder and b) Shooter's culpability is strongly mitigated].
1. If the DA does not tell counsel for Driver and (particularly) Shooter about the conversation, do you tell/ may you tell Shooter and Driver's counsel about the conversation?
2. Is there a difference if you ask Client if you can talk to Shooter's and Driver's lawyers about the conversation and Client says, "No"?
3. What if the DA's argument at trial directly contradicts what Client said about Shooter?
