Would stricter gun regulations decrease the number of violence crimes committed in the USA?

I believe so. Stricter gun control would certainly decrease the number of deaths and injuries from guns. You can’t shoot someone if you can’t get hold of a gun. In countries where guns are almost totally illegal, such as Japan, gun fatalities are virtually unheard of. In countries where gun licenses are given out but you have to prove why you need one - and the answer can’t be “for protection” - like Australia, the rate of gun fatalities is much lower than the USA, which has looser laws. Australia tightened its gun law to include this stipulation in 1996 and the next year the rate of deaths dropped by 56%. Here in the UK it is very rare for anyone to have a gun. Sometimes here in London you see a police officer who is part of special protection team, for example around the foreign embassies carrying a gun in a holster and it is so unusual I can’t help staring at it and feeling a bit frightened. And then I look away because I don’t want the officer to think I am staring at them in a hostile fashion and threaten me with the gun! Obviously that is unlikely but it feels like people with guns can be unpredictable and feel more powerful. I get this impression not just from American TV shows but the news as well.
