A proffer agreement allows you to provide information to the government with some assurance that your words won't be used against you in court, usually as part of plea negotiations. This is a high-risk strategy that should never be attempted without a criminal defense attorney.

A target letter notifies you that you are the target of a federal grand jury investigation and likely to be indicted. If you receive one, do not speak to agents. Contact a federal defense attorney immediately to intervene before an indictment is returned.
