Shot and trapped
Seems like one has to say the painfully obvious: If there are no guns, there are no gun incidents. The basic principle to strive for a safe and civilised society are not trusted to the state. Instead gun owners seem to believe in Social-Darwinism. May the world be bad, may it be full of "manics", the issue for the average American gun owner might be that a maniac is being quicker in pulling his gun. Game over.
