We'll start with this. Whenever a gun discussion, this always comes up. I don't understand why people seem to think that those wanting to keep their guns are some paranoid cowards who undoubtedly have to have a gun on their person to feel safe. It's called being prepared. I'm no hiker, but I'd imagine that most take extra food/water along, ya know...just in case. Which is the exact same reason why people carry, just in case. That concert hall in Paris-100's of patrons, 2 shooters. Perfect example of where just in case would've saved lives. San Bernardino, same case.
While the difference is vastly different, at it's core, it applies, to me. Gay marriage. I can't recall how many times I heard/read/saw people shouting to all who would listen, "it's our(their) right!" and people applaud them for standing up for & demanding rights afforded to them. Why should it be any different to us who want to carry our guns?
As for loophole-whether or not it's real- I don't know, as I've never been to a gun show. IF that is actually happening, then of course it has to stop. But, as mentioned by a few people, private sales are private sales, regardless of they take place at a gun show or someone's living room. So, how do we deal with that?
Mental health. Nobody wants to deal with problems these days. "give them a pill" is today's prognosis. I can't even count the number of pill commercials I see for everything under the sun. Another problem is more often than not, the people who do the shooting go under the radar-nobody knew they were suffering- or they say something, usually 'net wise, and people around them reply, "didn't thnk they were serious". There's that 'see something, say something' rearing it's ugly head. "oh no! I don't want to be seen as a racist or that I fear Muslims!" *facepalm*
I think that's it for now.
