“Alberto’s predicament dramatizes a core principle: making a statement to the police is never --never --in a criminal defendant’s interest. Talking to the cops is generally a bad idea, even if you’re the one who called them. This is true whether you are Martha Stewart, who secured a jail term when she foolishly decided to make a voluntary statement to the authorities, or Alberto, who fancied himself a clever jailhouse lawyer, confident that he could get even by manipulating the cops. It is one of the few things that every criminal lawyer will agree on: in the crucible of police interrogation, the police will always win.”
