The agencies I use are all outcall - to my abode.  There is no physical place to bust them (it's just a phone line that gets
routed to which ever phone girl is on during that shift) which
means there's no one to observe or complain about what is going on.  Because of that, to LE they don't exist.

Could LE get phone records and prove what's going on?
Of course, we've all seen 'Law & Order' where they "pull
the lugs" (that is, obtain phone records).

I think LE isn't (or is less) concerned about what people do away from the public eye - as long as there's no obvious collateral damage, like there would be for, say, drug dealers.

The outcalls mentioned above are surely an extremely low priority on the LE list.  It's like they don't exist since
there is no observable event that indicates something is
happening.

In call places are another story since there is a physical place where things can be observed.  LE doesn't just come upon these places (unless they're stupid) - neighbors, landlords, or other disgruntled associates just have to make a call to complain and eventually they're gone.

outcalls don't often get busted is that police  usually need a warrant to enter someones home w/o their consent. And police in NY can't arrest w/o  a  warrant for ANY misdemeanor (which is what solicitation,  prostitution and patronizing a prostitute are) UNLESS IT'S COMMITTED IN THEIR PRESENCE. They've got to be there.


Neither the "warrant nor  nor police presence is likely to happen  during an outcall engagement absent  some police participation (ie encouragement) in the act, which may or (alas) may not be entrapment, depending upon the egregiousness of the police conduct, and whether the parties were predisposed to the act.
