I would be leery linking a Constitutionally guaranteed right to an FBI Watchlist or No-Fly list.
Right now we have a very clearly defined set of criteria one must meet to purchase or own a firearm. For some reason our govt chooses not to enforce those requirements, not to prosecute violators, and not to heartily prosecute any crime committed with a firearm. Indeed, we see states restoring lost rights to convicted felons. Yet I see discussions about Watchlists and No-Fly lists?
Who controls the Watchlist or No-Fly list? Is there only one of each list? How does a name get on them... or off them? How would we feel about a govt watchlist that determines some individuals who are not allowed to worship in a mosque? That's another Constitutionally guaranteed right. Or how about an FBI list that decides some people can be retried for a crime of which they were previously acquitted? Another guarantee.
Please don't waste time arguing about my analogies. I'm just saying I am leery of letting some watchlist or no-fly list, created and controlled in secret by a govt institution, revoke a Constitutionally guaranteed right. It is a slippery slope.
