How about this, the USA has both one of the highest murder rates, and some of the most relaxed gun laws in the first world. I am 3.5x as likely to get murdered in the USA compared to the UK. Around 66% of murders in the USA involve a firearm compared to 7% in the UK.
I am 33x as likely to be shot to death in the USA compared to the UK.
Don't you think that someone with easy access to a gun is more likely to commit murder in the heat of an argument compared to someone who doesn't?
Do you really believe that easy access to guns is a good thing?
Do you really believe that having access to guns will prevent a dictatorship in the USA? I don't. I think that would ensure a bloody civil war. As someone else on here pointed out recently, non violent mass protest is far more likely to effect change because a striking workforce can cripple an economy rather quickly.
