Recently considering patronizing some providers in Chi-town.  I'm a relative newbie and still exceptionally cautious, and thought I'd do a little research to assess risk of LE repercussions before proceeding.  What I learned kinda surprised me.

If you are so worried about these situations and who you are visiting you need to do your homework on your provider as we do on our clients. If your numbers bug still itching at you, I don't think this is the hobby for you. It will make everyone uncomfortable involved.

Follow some simple rules and you should be fine.  Always go with a well reviewed provider and use discretion with etiquette.   Stay clear away from the Back Page.  If your so paranoid that you can't enjoy the experience than maybe it's not for you and you would be alone. I have many friends that can not get past the fear of getting "busted".  Everyone has their own comfort level.  Good luck.

separate Call Operations (agencies?) and Street activity from the total?

Before you decide to see a lady who screens or doesn't screen, you need to do your research to make sure she is legit. Then you make sure you like her personality. Then you go through her screening form, which is a sign LE isn't in and out of her door, and also a sign that she understands the need to be careful and well informed.

Law enforcement has two goals. The obvious one is punish offenders. The second is to cause people, like you, to weigh the risks of involvement in illegal activities.  

Your one review is of a girl in NY who doesn't appear to do much, if any, screening.  That is a where the risk comes from - from girls who don't screen.   To be honest, with your one review, your TER history isn't going to get you into any of the reputable ladies here in Chicago.  You'd have to either be a member of P411 with multiple OK's (if you are new, that's not likely) , or be prepared to hand over all of your personal information directly to the lady or through RS2K.    Good luck and be careful.

Just do your research & find providers that are well reviewed...  

Likely most of those busts are in worlds far different from what we know here. What can be charged as "prositution" has a wide range, most of which you may never come close to experiencing considering you're here now.

My opinion on the whole LE and arrest thing, has been that they catch the low hanging fruit. I am not saying this to say that I don't feel that screening, discretion and caution aren't absolutely necessary- especially because our very own Sheriff, Tom Dart, seems to have a hard on (haha) for providers. But, if you are patronizing a well reviewed, high end girl who screens, you should be just about fine.  

Another thing I'd like to add.  LE generally looks for cars.  Because this is America, and by golly, everyone wants the freedom of the open road.  In their very own space on the I-290 parking lot.  So my M.O. is to take public transportation whenever I can.  Chicago has plenty of it.  With so many people on buses and trains, each going somewhere, not to mention all the pedestrians downtown, what you end up doing is hiding in plain sight.  I've walked right past LE on foot patrol once, on the way to a provider's hotel, and barely even noticed them, save for a quick glance at their uniforms.  I'd have a harder time relaxing when driving to a suburban hotel, where LE looks for cars to pull over (less crime = ticket-seeking behavior).
