SupersonicMax said:If guns are difficult to get, it will have a dissuasive effect those prone to commiting a crime. It will never stop violent crime entirely; there will always be people going the extra mile to get the weapons and shoot people. But it will, imo, certainly reduce the likelihood of occurrence.
There is a big difference between "difficult to get" and "difficult to get legally". Firearms are always easier to get illegally rather than legally, here and in the US.
Inability to obtain firearms will not deter someone bent on killing. See Nice (truck), Air India (bomb), World Trade Centre 2001 (knives and airliners), Blue Bird Cafe in Montreal (gasoline and matches), a nerve gas attack in the Tokyo subway, the Alfred P Murrah Building bombing in Oklahoma City (fertilizer bomb), and some mass slashings with swords and knives in Japan and China.
