“Sorry to disrupt, but I’m here for Mr. Innocent.”
One of my favorite things to do at this job is to show up at police stations. If a client is inside an interrogation room, manages to wade through the coercive Reed Technique garbage and get a call out to me, I’ll drop almost anything I’m doing and try to get there if I can. It hardly every happens, though.
Cops play all sorts of games to prevent it- despite what the Constitution says.
If I can talk to the cop directly, they’ll do everything they can to interfere. My favorite is when I ask “You’ve arrested Bob Innocent, my client…” to which the response is always, “No, sir, Mr. Innocent has not been arrested“, Because, as you know, even though a man is handcuffed and locked in a police interrogation room, he might be arrested to you or me, but that’s not “arrested” to the cops.
So, you have to say “detained”. That’s the magic cop word that means “arrested” to everybody else. If you don’t use their magic words, they play dumb.
