Europe did what you wanted...banned and confiscated guns....
The Europeans then went on to murder 20 million innocent men, women and children in just 6 years......not war dead....civilians rounded up by left wing socialists and murdered.
Gun murder in the U.S. over our entire 247 year history? Around 2,470,000
At the same time, Americans use our legal guns to stop rapes, robberies, murders, beatings and stabbings......and like this event, mass public shootings, 1.1 million times a year, according to the Centers for Disease control....
I'll take our guns and let the Europeans murder their citizens.....
