The reason for any violence comes down to the values and morals - or the lack of.
If one has morals and values - has respect for life and others - violence is not necessary nor does it erupt when more rational options are available.
Seizing weapons will not work - when the individual lacking everything mentioned above does not have the morals, values, and respect for life - but replaces those with hate, self-indulgence, and lust for evil.
Backgrounds checks won’t do 1 thing to stop this - what must be done is re-introducing the Christian values that our Forefathers brought with them - established in this nation - and where children were educated at home first with the values and morals of being a decent person that shows respect - then sent to school to learn the ABC’s and math.
The recent massacre is due to a boy that grew up different and his peers - instead of aiding him - propping him up - including him in school activities and protecting him from bullies - shunned him, degraded him, and cast him aside - with the coupling of negative replacements - be it violent video games, Hollywood movies, and the desire to bring forth evil - caused the shooting.
Barry Sh*t For Brains should concentrate on banning people like that - to include himself - because Barry has those same negative values that go against the gain of traditional US society...
just some thoughts...
Most of my friends own guns and plan on getting more. That said, I once met some one from New York City who literally (I kid you not) trembled at the sight of an antique revolver pictured in a book. Up until that point, I had never met anyone like that in my life and was dumbfounded by the reaction.
I live in a rural community where most folks are armed and hunt often. Crime is very low here and arms come in quite handy against dangerous wildlife here (mountain lions, bears) that come near our homes.
