Phoenix seems ground zero for all the busts including felonies going after in private consenting sexwork.
I have read many police reports, grand jury indictments, probably cause statements and attended various court hearings.
If one is one fortunate enough to be the target of LE they will often stake out your parking lot watching apartment, home or a massage parlor for often six months recording all the license numbers of cars coming and going.
They also look for any tickets etc. But they will take no action just sitting in lots or watching from across the street (no real crime of course happens in Phoenix).
Then when they raid usually with massive swat team force, (dangerous breasted women), they will charge all the workers with criminal enterprise felonies, merely by "association" even with no evidence of prostitution against most individuals. The license plates tied to the women are enough for probably cause as long as they also have cause like from a UC that a offer for say a HJ was given.
They will also observe customers going into and coming out. LE will follow the guy and look for any minor traffic violation they can find (or any unpaid tickets from running license). Then do a traffic stop and then question the guy showing any web ads, reviews etc of the targeted establishment.
The guy gets scared and perhaps assuring him they will not prosecute him if he "talks", he often admits he paid for sexual services (like a HJ) at the massage parlor, or sex at a companion etc.
The gals are rounded up and bail is often $5000-$10,000 or for any owners usually $100k and in one case $1 million. No one is under aged, no pimps, just normal massage places, tantra "temple" or two gals working together.
One indie gal was raided by SWAT just for escorting without a license. After they broke the down down and open her mother came to bring back the pizza they ordered. Elderly mother had swat team assault rifles pointed at her. She did know of her daughters chosen profession it was only the big guns pointed at her that was a concern !!!
