Simply keep your mouth shut! Cops will try to scare you by using all kinds of tactics; namely lies and deceit. Like someone mentioned earlier, merely being in an "eatablishment", licensed by the city/county, is hardly a crime. Sure, LE may know what goes on there, but there main focus when raiding a place is to get Johns to cop to a violation of the law.
Solicitation and/or any related offense is certainly something that one does not want on his record. By pressuring a John into "cooperating", LE's only concern is getting him to admit to a crime so that it can be used against him in court. LE has no interest in letting anyone off the hook if they can get a confession. They use this BS tactic, when they have nothing, so that you will think they are trying to help you! What a load of crap! It's like when you're doing 80 mph on the freeway and the cop who pulls you over says he's doing you a favor by writing the ticket for 75 mph. I still have to pay the ticket. If he really wanted to help me, he'd have acknowledged that I was polite and cooperative and let me off with a warning.
I'd like to say that they have bigger fish to fry, and indeed they do, but it's much easier to make money off otherwise law-obiding citizens, than hardened criminals. All though grossly corrupt and unfair, most of us will or need to throw money at the problem to make it go away.
