Firearms - whats the most plausible solution?
That's a pretty sharp rise. So what caused it? Paranoia, the wish to defend yourself maybe. Cause could also be a society that is scared witless, due to the last president who was in office, or this president is too soft and lets all the laws be passed without really paying attention or caring.
I know this question has been posed a few times recently, and frankly the whole statistic pales into insignificance, compared to all the wars and atrocities that are going on in the world. IMHO US citizens react like a bunch stung by bees when someone shoots up a shopping mall, but give less than a cent for what's happening in the Ukraine, for instance.
If it was up to me, all weapons on this planet would be melted down and the production banned for the foreseeable future, cos the human race ist not capable of self control.
Opinions?
