When you are on the playground and see a kid doing the same retarded jump and hitting himself over and over, you do try to help him in some way. If the vast majority of civilized country managed to remove and tone down guns and have seen very good effects, why wouldn't they share the info with US? The fact that US doesn't act is what shocks us, the rest!Look at all these people from not-USA telling people from the USA how to behave.
