“My objection to the no-fly no-buy proposal, while certainly based on Second Amendment grounds, is more broadly one of opposition to any system that allows almost entirely unaccountable bureaucrats to restrict constitutional rights without notice, recourse, or accountability. No matter how meritorious you believe your cause to be, excising rights at the behest of a government executive or agency should terrify any right-thinking person. If you think the terror watch list is merely an affront to the Second Amendment, you’re not paying attention.
It doesn’t take a lot of effort to create a gedankenexpriment where the erosion of rights embodied in the Fourth and Fifth Amendments is the next stop on turning the Constitution into a Chinese menu where one party removes rights from Column A and the other from Column B. Just saying, ‘But guns…’ doesn’t make it less dangerous.”
Short and worth reading.
