It DOES happen elsewhere. The media usually keeps it quiet.

Up-voted. Yep, because all those other nations have outlawed guns and so only their . . . outlaws . . . have . . . guns. Ooops!

Still leftist virtue signaling is, apparently, its own reward. It's what they are good at doing.

The Oslo perp was known to the police in Norway and not deemed a threat to society...

OMG... NAILED IT

My condolences on the innumeracy expressed in your meme. Most years, the US has about 10 times as many MASS SHOOTINGS as Norway has TOTAL gun deaths. We average around 40,000 gun deaths a year.

40,000 > 4. You know, a lot more.

Population of 335,000,000 > 5,500,000
You know, a lot more.

Oh, let's go with the ratios! If those are the respective populations, then the US has about 67 times higher population, and as much as 10,000 times higher annual gun deaths. The math does not support your position.
