There are Federal courthouses all over Texas and plenty of Federal jails in the country.
What this means is the local LE and state types can't help the Feds in any way. The Feds want to bust folks, it's all on them start to finish.
Pretty much exactly how it is for "Sanctuary States" with people in the country illegally, or states where drugs that are federally illegal are legal in the state.
Being that one of the murder masters from massacres a bit ago is now the head of the ATF, I'm going to assume unlike immigration and drugs which the Federal government kind of goes back and forth on if they want to do anything about depending on the politician in power, they WILL have a raging hard on to show that you best obey or they will burn your family alive, kill your wife, murder your dogs, ass-assassinate you and all that good stuff.
So my prediction is:
1. folks who do stuff themselves and keep quiet and go about their life will have little to fear.
2. Those that setup a big commercial operation and go advertising themselves are going to get Hammered hard and fast
3. Those that brag about it on social media and YouTube and publicly give the ATF a big middle finger will get hammered right after they deal with #2
In my case I plan to just continue paying the taxes and waiting, but this bill does help me in that it means most likely I can expect the local LE to not be interested in harassing me over suppressors and demanding to see papers and such since there is nothing they can do in that regard.
