The more I thought about this and Senfronia, the more I realized what they want to do-Put teeth against the users of human trafficking sites, more teeth than today. SenFROnia has been trying to battle human trafficking for years if you look at the TX bills submitted.
While that's potentially laudable there's so many scenarios, like any poorly written law, that mean poor semi-innocent guys will get the short end of the stick. Lets say you hit a certain seedy bar that was busted on 610E for human trafficking about 10 yrs. ago (some will know what I'm talking about). Well as a visitor you know what they have and if it smells fishy...that guy knew that these were girls working in a shack and knew the bargain pussy was b/c of that situation. I don't give him much credence if he gets added charges or elevated charges.
However, if you're from out of town and ask a buddy where's the best spot, and he sends you to the same bar, 1st time there and you realize it's sketchy do you deserve a felony?
I think that us going to a spa will never have a problem. Today Mr. law doesn't visit a number of places, with more paperwork and harder legal barriers do you think he'll suddenly visit more spas or bust more Johns? Potentially but unlikely too.
TL;DR-
Stay away from the north side of town, that's Fro's district
Don't visit obviously sketchy / trafficked places.
You'll probably be fine.
