Only if the U.S. government also gets gun controlled. They shouldn't be allowed to send arms to radicals or use guns in illegal wars. Also they shouldn't be allowed to take actual radicals off and on again watch lists when it suits their Proxy War needs.
The so called gun banning for 'no-fly list' if they are Terrorist Watch List is highly abuse-able given the precarious situation of the U.S. Police State. The things that can now land you on a "terrorist watch list" are: Attend a political rally, Express yourself on Social Media, Serve in the Military, Disagree with a law enforcement official, and other nonsense. Everyone is high on emotions and politicians are simply acting for political gains and not thinking about the future consequences.
"In other words, there is no way to know whether you are on that list. Nor is there any way to know how to get off it.
That there is any list at all should give us all pause. It has not historically been the hallmark of a healthy democracy when governments have kept lists of people they didn’t like."
Also here is an article
from Jeremy Scahill, Ryan Devereaux who are actually liberals
explain exactly how it will be abused.
