How on earth do Americans 'cope' in Europe and other countries where carrying guns is illegal? The US must be a dangerous place if their society is in such fear that they need to arm themselves.
If people cared about it, they would rise up and do something to stop the killings but they don't. Just let them get on with it. It's the same with police brutality cases. The United States is a violent society despite the 'Land of the Free' BS.
