Shooting at Sikh Temple in Wisconsin, USA.

He probably thought they were muslim.

Its not like America is the only place in the world where people are killed by guns, 4 people were shot in Liverpool last night despite our gun laws that clearly make the innocent more vulnerable and are a mere hurdle for anyone who wants a gun to kill members or the public.

Just because a law won't prevent 100% of gun related homicides, that doesn't mean it shouldn't be implemented. Having more restrictive laws in place may reduce such deaths. To say that such laws make the innocent more vulnerable is completely ignorant - there have been over fifty massacres in the US in the last thirty years, tell me, how many of those have been prevented by civilians carrying guns?

The UK's laws won't prevent every shooting, but does that mean they are a failure? Absolutely not. The US's laws allowed the Aurora gunman to buy 6000 rounds of ammunition without raising any alarms, and have led to many deaths.

The US has the highest firearms related homicide rate of any developed nation, and one of the highest in the world. It is quite obviously a country that needs better gun control laws.

Why is this happening, especially in the USA

Perhaps, because the US constitution allows US citizens to bear arms?

But that doesn't mean that they are allowed to randomly shoot people!

America definitely needs to ban assault rifles and bring in more regulations such as background checks and limits on ammunition however I agree with them when the say they have the right to defend themselves. Britain on the otherhand is the exact other end of the scale where no one has weapons but the state, criminals and a few farmers and gun clubs. Gun crime has also risen since the UK's last ban in 1997 I believe.

I think NI is something we should look upon where over 100,000 people own firearms and there is no significantly larger amount of shooting in NI despite its sectarian history.

Perhaps, because the US constitution allows US citizens to bear arms?

It's awful what has happened, the gunman has been found dead now and thankfully not too many were killed. http://news.blogs.cnn.com/2012/08/05/breaking-reports-of-shooting-at-sikh-temple/

It's an absolute disgrace, where do they get the weapons from is it really just that easy to get guns in America? All those people dying for no reason.

Tbh it would be as easy to get a gun in Britian, despite its illegality here. I live in Birmingham and I'm sure that there's some areas around here where it would be really easy to get one and I've seen documentaries where people in London say that they can get a gun in 15 minutes. So it's not a case of getting guns, it's just the mentality of some people.

You also say that by allowing widespread ownership of guns, Americans therefore have the right to defend themselves (implying that we don't ), but surely we still have the right, just not the right to defend ourselves with guns. Plus the actual 'defending yourself' bit hasn't seemed to work, like I said, of the fifty or so massacres in the US over the last three decades, none have been prevented by gun totin' civilians.
