Persons living in American have murdered nearly 12,000 of their own using guns since the beginning of the 2017. Claiming their right to carry firearms is killing their security and stability as a society.

Paul,

One of the things that I object to is the Greens propensity to use a tragedy to score political points with such indecent haste as you did in the OP.
I also object to the exaggeration, ".... armed with an arsenal of automatic weapons, shot and killed at least 59 people, and injured over 500 others"

I doubt that he had any automatic weapons, as such weapons are strictly controlled and extremely expensive in the USA, the number that he killed is not in doubt but your claim that he injured over 500 is ludicrous, for it takes no account of the injuries sustained in the rush to leave the area. He may well be accused of being ultimately responsible for them but he didn't cause all of them in the manner that you intimate.

//You left a bit out, I wonder why?//

Because it wasn't relevant. It doesn't matter many decibels the damn things register: the fundamental purpose for which they are designed is to propel a metal projectile at extremely high velocity through human flesh, resulting in injury/disability/death.

That's the problem. That's why we need fewer of them, not more of them.

But just because the bit about silencers is of little relevance, it does not follow that her comments about putting politics aside, standing up to the NRA, and working together to stop this again are irrelevant or invalid.

Although they seem to have fallen on deaf ears in your case.

The truly evil thing is that there are no crazed gunmen, only paid assassins.

A senior citizen with no criminal record carries heavy loads of guns/ammo into a Vegas hotel/*casino* and nobody notices anything suspicious?
Shots are heard from more than one direction/level.
Antifa materials conveniently found in room (Why bring them?).

Crowd chosen to threaten Trump supporters: country music festivals attract White conservatives, not purple haired hipster communists and "oppressed" minorities.

It's America's problem to solve not ours; we have the most draconian gun laws in the world thanks to the Howard knee-jerk, so it is not going to happen here. Besides, gun killings are a cultural American thing. There is no significant pressure in Australia to ease gun laws.

I couldn't care less about the regular gun massacres in America, but I find it interesting that the first posters to pontificate about such things here are those who hate America and our alliance with it.

Putting politics aside?
Hillary doesn't know what that means.
Her opinion is obviously political.
