If you really think the court system is not rigged and you think your challenge to FOSTA has a chance, you are delusional.
If you are not sure if certain people pimp, then I would recommend you cruise on over to the Circle K at 27th Avenue and Indian School, probably anytime between 10 pm and 3 am.
The judicial branch is bought and paid for by a certain group. More so than any other branch of the government. Dave's legalization case and your constitutional challenge case will be the same outcome. The constitution on means not what it says, but what the legal system says that it means.
It does not matter that 17% murder rate has fallen, because the government has no duty to protect anyone. The supreme court ruled so in various cases. See Castle Rock v. Gonzalez, 545 U.S. 748 (2005) which also invalidated "shall arrest" statutes.
The aim of the government with FOSTA is to protect impressionable young providers 18-20, to prevent them from providing so they will then get knocked up and increase the population which will increase the tax base. Older providers (some over the age of fertility even) the government knows it cannot change hearts and minds of the older ones so it will be content seizing assets (house, car, bank accounts) of older providers and the FOSTA will help them get search warrants and shut down websites. I envision a profit sharing system similar to the drug profit sharing government system where the state LE provides evidence for federal court civil forfeitures, etc. Assuming the younger providers are taken out of the equation, the profitable system of taking down agencies and rich older providers will be relished by the government.
