How about that guy who fired into a crowd from the balcony of a hotel room in Vegas?people who have an inkling to kill someone (murderers/serial killers) don't need guns...heck terrorists don't need guns to inflict damage. guns main purpose is a deterrent...it tells you "back off" or "better not have stupid ideas"...during the days of the wild west....everyone gets to carry a pistol and if you want trouble...you will get it...now we're not the wild west that's why we need to have license to carry....American laws are way different bu IMO, it all depends on how responsible a gun owner is...
You think he'd have killed 50 people if he'd just had a knife?
