But usually it is a response from complaints from neighbors nearby hearing and seeing what is going on and then calling LE to complain.

Whether or not LE has actually done a sting type operation with outcall I'm not sure.  LE likes to have control over the area to avoid problems like a pimp in the next room with a gun, etc.

So, try it out, but do know that there're no guarantees.

But if you are going with unreviewed gals for outcall, you may need to call LE after you have been robbed or mugged.

You asked if there are any other possible dangers to doing outcall?  Read on.

into an unsecured setting such as a hotel room is not particularly great.  I am good friends with a senior prosecutor in a large southern California city who told me recently that ALL of their prostitution cases are from girls they go after off of Backpage.  They only have so many resources so tend to go for the low-hanging fruit.  That said, as others have noted above, there can be exceptions to this but they are almost assuredly few and far between.

I have been engaged in this hobby for over 10 years now and have never encountered a problem.  Of course, I have also focused my attention on porn chicks, one of the reasons being that when I go to the room and Trinity St. Clair opens the door, I'm pretty sure she's not LE.  

They WILL certainly set up stings where you go to them in hotels, not a doubt in my mind that I spoke to one once.  While we were on the phone, she started getting real fact specific: "Oh, so I'm going to give you a blowjob and we'll have sex for $300?"  Umm, no, not tonight, officer but thank you for the offer.  

The other way to avoid problems is to use this site and make your decisions from the neck up.  I don't remember ever seeing someone who wasn't a porn chick who didn't have at least 5 reviews or was recommended by someone with at least that many reviews.  Here's the deal: there are cops looking at this site and all the others as I type this but again, they just don't have the time, energy or inclination to get as involved with things as you might think.  

Bottom line: invest in the VIP membership and use it wisely.  Not only will you be safer, if you stick with well-reviewed girls, you're also much more likely to have a great time.  I can count on one hand the number of times I've been disappointed doing things that way. Knowledge is power, friends.
