What I mean is that preventing the general public in the UK and Greece specifically from owning guns has meant that gun crime is virtually non-existent compared to other forms of crime.
I feel a great part of it has got to do with the general access people have in the US. The overwhelming majority of guns used in crimes in the US are guns legally manufactured and bought in the US by US citizens, which are then either stolen or used in criminal activities.
Lesser guns for the public seems to equal lesser gun crime in that society, or at least does where I'm from.
But given the amount of guns in the US, I would NEVER be in favour of strict gun laws there. It would be murder (literally) on the honest law-abiding citizens.
