Competitors mostly and house wives are the ones that complain to uncle leo about a spa. When you look at historic actions by the po po, they do undercover, then get a warrant to do a raid, nowadays multiple spas at once, they go for it all: prostitution, trafficking, and unlicensed & undocumented staff. Guys will get swept up into it if you are there. Remember your rights, DONT SAY ANYTHING. I really don't know how cameras in the parking lot or license plate scans would help the DA in any way.
As for Sunny Spa, they are a known AMP by all, it is not a secret. I have not been there in awhile because my experiences were not great and there have not been other reviews to change my view.
