Stephen,
I don't think anyone here is arguing with the fact that wearing a seatbelt is the smart thing to do, and that it will save you from death or disfigurement in an accident. I think the main problem is that laws are being made to protect us from ourselves, and most people are sickened by this. When looking at the guy who died from the pepper spray, he wasn't injured or probably even involved in an auto accident the day he wasn't wearing his seatbelt and was given a ticket. He probably got it along with a speeding ticket. It's just that now he is dead, and over a stupid law that was put in place because 'he should have known better and worn his seatbelt.'
It's common sense to wear sunscreen (for most people, anyways) when you are going to be exposed to the sun for 8 hours straight, but some people may not listen to common sense and get skin cancer. Who knows, they may even somehow cost us taxpayers money. That doesn't mean we should be required by law to apply SPF 15 or greater just because we're going to be in the sun for a few hours.
I'm more arguing with the fact that the law is pointless, rather than directly addressing this particular situation. If he pulled a gun on the officer, he should have been pepper sprayed. We just don't have enough info to debate that.
