Because shooting back will never work, right? Too bad the cop who shot the jihadist didn't know that, she could have saved herself the trauma of being shot by the mass murderer she stopped.
Shooting back works to put an end to a situation like this, but it will never prevent it from happening in the first place and it will never prevent mass shootings from resulting in the deaths of people in the general public.
Arming everyone is fine, but it's not going to stop mass kilings and it's not going to prevent people from getting killed in the first place. The killings are going to happen. All that is going to happen is that the perpetrator will be shot (but then again, they usually shoot themselves anyway and kill themselves).
And the fact that the targets of these killings are chosen by their killers, and always consist of groups of people certified and verified by their environment to be unarmed, is just a big fat coincidence, right? Nonsense - you have no grounds in either statistics nor common sense. Anywhere people are known to be armed, violent crime goes way down. And multiple killings always happen against known unarmed groups. Hell, they're multiplebecause no one can shoot back!
You're just trying to stir up trouble. Your anti-gun arguments are long disproved, and you're using the gun issue to try to shift perspective away from the fact that this was a Muslim jihad event.
But that's what it was - a Muslim jihad event that shows the real teaching of Islam, and directly casts into doubt the safety of everyone in the country in the presence of any Muslim anywhere. The fact that this killer was a psychiatrist trained to help people recover from trauma just underlines this point - Muslims lie and get into positions of trust so that they can commit jihad murder. They plan for this, they intend it, and they do it.
Which makes me wonder - is this the real reason you are so sure "the killings are going to happen"?
Because the one thing that can stop these bastards in their tracks and save lives, and deny them group targets of opportunity - the constant arming of the population - you are against. Oh, you say you "have nothing against" people carrying, but then you declare it "useless."
But don't worry, there are plenty of Muslims who will encourage your efforts. Maybe you know some of them?
