Sorry to disillusion you but yes there have been 7 mass shootings in Colorado this year it seems they didn’t all happen in Denver.
Don't be sorry, the disillusion is all yours. I checked out those shootings and it looks like 2 of them might actually be mass shootings, the rest are not. I'm guessing this is the same website that put up the fake report about the number of mass shootings where no black people were involved, it's been all white people? If you check the stories from CO, all but 2 of the shooters has been confirmed as being black. 1 case was a white guy and the other case we don't know because they haven't caught the shooter.
The article is “Here is What We Know so, Far About the Shooting in Downtown Denver” it is from Time Magazine.
I checked the article and they use a BS source for their shooting stats, sure it might have "all" the shootings from the US, but their classifications are weak and bias.
What you said was it would take a professional gun smith to modify an AR-15 to full automatic but this case go to show that a professional is not required. It looks like just any old mass murder can modify an Ar-15.
If I said anything, I said it would take a gun smith to make sure it was done right, and so far we don't know if he did the work right, he was caught before he was able to commit his crime.
The shooting in the Alabama mall sends a clear message to the gun nuts with a gun. If there is a shooting and you decide to pull your gun to shoot the bad guy when the police arrive and see you with a gun, they are going to shoot you no questions asked. So much for the NRA’S theory that if everybody had a gun that would solve the problem. The guy that was killed in Alabama had a permit to carry a gun and no doubt decided to play hero.
With the new Police strategy of rushing headlong into a shooting has resulted in the officers being killed. When you rush headlong into the scene of a mass shooting, they are going to shoot anyone holding a gun. More guns more dead people.
One case is all you got? I could provide plenty of stories where this didn't happen, so take your bias and try again.
