Look, you're trying to take the side of a guy who is interested in helping his fellow American brothers and sisters. He is trying to save lives. At worst, he is trying to reduce insurance claims. This seems reasonable to you and me, but not to the government.
You are going up against an organization of people who knowingly allowed the stoplights to be set in such a way that increases property damage, injuries to humans, and also deaths. Why would they do this? Two reasons. You don't matter and because it generates additional revenue.
So, on one side a generous person willing to give of his time and expertise to help his fellow man. On the other a faceless, blameless, murdering gang of thieves. They indiscriminately kill children so they can have additional money in their coffers.
Are you surprised that these hideous bastards would respond with an attack?
By their standards what they did to this guy is considered irrationally polite. They got what they wanted, which is more money, but this time they didn't have to kill anyone to do it. They probably look at it as a win-win.
Burn them all.
