Anyone can be put on and FBI watch list, it should not be criteria for stripping people of constitutional rights

You get put on the list for a reason. Your comment really lacks any logic.

Sometimes that reason is
-you involved in a political movement that the government disapproved of.
-you go to the "wrong" church, synagogue, mosque, ect.
-you have the "wrong" friends
-you follow the "wrong" people/groups on social media

Yes, you're on there for a "reason"
That doesn't mean the reason is valid.

On a side note, I don't know if he owned a gun (I would consider it unlikely) but it is a fact that he was on FBI watch lists.

So you're saying a watch list from the FBI is not valid? What you posted is exactly why the list is there. If you associate with possible problems than you have the possibility to be a problem. Exactly why the list is needed and enforced. What is happening now is exactly what happens when it is NOT enforced.

Being looked at by the FBI does not mean you committed a crime, the reasons why the FBI would watch someone are arbitrary and do not justify revoking constitutional rights, by supporting such nonsense any and all constitutional rights can be suspended for arbitrary reasons. Think of it this way. Would you want Donald Trump to have the means to strip you of any and all constitutionally protected rights without due process for any reason what so ever? You do realize government agencies like the FBI or IRS are often used as weapons by those in political power at the time against opposition political points of view. Your short sighted lack of forethought is astonishing

Hmmmm, let's ask the 49 Orlando victims about not adhering to the FBI list. I don't associate with known criminals or terrorist organizations. Your lack of insight teeters on the edge of retardation.

Almost ALL mosques have a suspected terrorist member(often a recruiter). Not everyone at the mosque (or even a majority) suspect such. They may be friends with them without even knowing they have terrorist ties. Anyone at any of those mosques could be put on the watch list. This could be used to strip ALL muslims of constitutional rights. Are you really okay with that. It is eerily similar to the idea of all Muslims having to register with the government. Also, using the "just in case" logic justifies refusing to accept any refugees, as well as deporting all immigrants from such areas. Again, are you really okay with that. Anything that can be done without due process to others, can eventually be done to you. If you're still okay with that, you truely do not comprehend the implications.

All Mosques SHOULD be on a watch list. That's the safest place to stash weapons. I do support not accepting refugees from hostile countries and putting immigrants through the vetting process like it used to be. I'm second generation Italian, my grandfather came here in 1910 through legal channels and it should still be that way. I believe in deporting all ILLEGAL immigrants. If you do not have a Visa then you DO NOT BELONG HERE. Your thinking is exactly why this country has gone to shit.
