I recall hearing some time ago, that for Super Bowl week/weekend, [They] "bring in" women for prostitution purposes. The local talent just isn't gonna fit the bill.
I think this is common knowledge. Only now it seems to be being acted upon (thankQ President Trump).
p.s. Underworld (Russian Mafia/Ukrainian Mafia) like to traffic in eastern European women. I assume the Chinese gangsters do Chinese women. Mexican gangs/cartels the Hispanicals. And so on and so forth.
But yea, the Super Bowl is the Super Bowl of human trafficked hookers (sex slaves) too. Or so I've heard.
For a beginners remedial course. Watch season three (I think) of The Wire.
I presume that Fed LE want to catch and maybe did, the financiers and big guys in the trafficking “industry”.
