I've never owned a gun, but if I did, I would shoot myself in the head so someone would have to clean up the mess, pick up the brains and skull fragments.
Concealed carries and open carries don't stop mass shootings or actions by crazies because mass shooters and crazies target gun free zones almost exclusively.
"Only ten percent of incidents took place in “gun-free zones”, or areas where civilians are prohibited from carrying firearms and there is not a regular armed law enforcement presence (armed security guards, for example). The vast majority of incidents—63 percent—took place entirely in private homes."

I don't give a fuck either way what laws Americans want regarding guns but still.
Why on earth would you cite incidents in the home in relation to me talking about mass shootings?
