Seems as though the GOP Senate are equally steadfast against any discussion on limiting access to guns as they are to eroding what little privacy US citizens retain. How can one amendment be so untouchable that it actually harms another?
All of those things have been proposed this year or are already enacted.
On the one hand, people who have been found to be a legitimate danger of terrorism by a reasonable process including due process of law arguably shouldn't be able to buy guns. Or fly on commercial airliners.
OTOH, I can also see a reasonable argument to be made that the various terrorist watch lists (including the no-fly list) do not meet the appropriate standard of due process for either or both of those consequences.
