A little bit off topic, but how does that work in practice? How do I find a lawyer instantly? Do Americans generally have a lawyer contact just in case?
The bigger issue is that you'll then be paying at least $300/hour for their services. So now you're burning money to have this conversation just so the FBI can fantasize about being heroes.
Don't talk to the police without an attorney is good baseline advice, but also misses the mark in many ways. Any way you look at it, getting into government crosshairs (whether it's merely civil questioning or a literal gunsight while being used for target practice) is a perverse reverse lottery that survives because of regressive politics and the just world fallacy. And this won't change until there is reform that fully compensates suspects/witnesses/etc for their time, expenses, and other damages incurred as a result of erroneous law enforcement.
FWIW as much as I hate the term, having a relationship with an attorney that you could call for urgent representation is a form of privilege.
"call a layer" doesn't just suppose you have their phone number, but that you have the on a retainer, because without being arrested, there is no emergency representation procedure for you.
edit I'm laughing at the impracticality of it all, but it's unhelpful, here is the deal : if really you think it's lawyer time, call a random lawyer of your family or business, anybody with a bar exam, and they will refer you to a co-worker of their best guess your case is about. And also, if you call right there in front of the police, you have forfeited your client-attorney privilege because you purposefully placed your call in front of a third party (crap, I went cynical again).
