I'm afraid if there's an unshaken belief Shangri-la can be obtained by banning weapons that, in one form or another, have been around for about 1,000 years, rather than addressing the 'root cause' in the mistaken belief of "No guns, no killings", and that potential perpetrators will just say "Oh well, I'll volunteer at an animal shelter instead", reality will be a shocker.
