A personal view
Every American I've met has been very polite, friendly and a joy to talk to.
To most Brits, the portrayal of America in the media is of a mad, scary, war mongering and unpredictable populace that seem to shoot each other at the drop of a hat. This is mostly due to the TV shows aired over here and new items that show hyper US military personnel shouting and screaming like Joe from Family guy, I guess.
It seems to me the guy in this story was just unlucky. If they bloke driving the truck didn't have a gun, but still wanted to cause harm, as said before, would just run the guy down.
I personally have no real view of American gun control. It's up to them, nothing to do with me (until I turn up on your shores again of course. I've only felt unsafe once when we walked from the strip down to Fremont Street in Vegas, but that could have happened in any major city, anywhere in the world).
Two other points.
1) I absolutely loved blasting away with handguns, rifles and the SAW at 'The Gun Store' in Vegas, was a real treat for me having never even handled anything more than a 12 gauge before.
2) Being a proud Yorkshireman, I'm glad Dana W enjoyed her time in Barnsley (I'm hoping she's talking about the Yorkshire town) . :)
