to see it as the reason they're the only country to constantly have mass shootings.

They'll bring up one random case where a bloke defends his house from a home invasion as sufficient reason.

This bit beggars belief - Mr Card is a trained firearms instructor at a US Army Reserve facility in Maine who was committed to a mental health facility for two weeks earlier this year. The document also said Mr Card had reported hearing voices and had threatened to carry out a shooting at the military training base in Saco, Maine.

Didn't think to perhaps remove his guns at that point!?!
