What attracts bees - honey. What attracts LE? If you were LE and are being measured in terms of how many arrests you make, where would you concentrate your efforts?  Let me think - high concentration of relatively cheap hotels, high percentage of Backpage ads listing the area as location, reputation of city for agressive tactics, reputation of hotels for cooperating and even requesting assistance from LE.  

The last time I tried to visit a provider in a hotel in that area, well over two years ago, a patrol car circled the parking lot 3 times and then parked by the side entrance where the lady had told me she would meet me to let me in.  I bailed.  And she was a well reviewed one as well.  I expect the hotel staff had made a phone call.  

Same thing applies to BP and BC.  

There is always a risk with hobbying. Its prudent to reduce that risk as much as possible.  A bit like choosing to park your BMW at night on an unlit side street vs on a busy street with good lighting
