Well the Irish (IRA ),Italians ( Mafia ), Spanish (ETA ), Sweden (That island shooting ) etc etc etc . have gun laws an they seem to be able to obtain them easily enough. An they certainly have no problems with using them indiscriminately.
Point is laws are a load of tosh.
People have to want to not shoot folks.
Generally speaking it's people suffering from mental health problems who usually want to kill people, especially those who commit mass shootings.
And facts are facts, in the UK and Australia, to name but two, gun deaths are extremely lower than in the United States. The difference is plain, it's illegal for most of the population to own a gun in UK and Aus whereas just about anybody can own a gun in America.
And look at the deaths from guns in America, it's obscene, imo.
And the argument that organised criminal factions can obtain guns doesn't wash, of course people can obtain guns illegally, I could if I wanted one, but I don't think I need one, I have a large sharp knife, a baseball bat and a very sturdy front door (The only way in, 6th floor) so that'll do me.
As for no laws, that's foolish, imo, I tasted anarchy here in London several years back following the shooting to death of a man by police in Tottenham and it wasn't pleasant. Countless incidences of mugging, burglary, violence and rape and those were just the ones I heard about, people were literally too scared to walk the streets.
Our laws - and our police - aren't perfect, far from it, but for the most part they work and I feel safe walking the streets where I live 24/7.
