True, but they could easily use the list then give Due Process. If you find you cant get a gun because you are on the list... then demand the government prove the burden in Court, if they cant, you get the Assault Rifle.
They cannot "easily" do such a thing. The main problem is you won't know if you are on the list or why you might be denied. Even with the new "rules" proposed by the Ds there would still be no due process. You get on the list because of suspicion, and undefined terminology ensures you cannot get removed through the courts. If you should guess you are on the list and that is why you were denied access to what you have a right, the left proposed you have 60 days and only within that 60 days can you even sue for your right.. At that time the proposed new rules allows the government to use redacted documents as evidence for a "reasonable suspicion"... Even the court cannot read the reasons, they're redacted....
The reality is, this list already has names that should not be on it and using it as the measure to deny US citizens rights is unconstitutional and not, as Obama would say it, "Who we are."
Imagine a list like this that limited your right to vote, then imagine Trump in charge of "reasonable suspicion"...
A list based on suspicion is not "due process" and the proposed "fix" is worse than the risk.
Way to cover your bases. Who knows until an actual terror act is committed?
