What's up with the people who object to photo radar on the grounds that "They didn't mention it in their campaign platform"?

No, this issue was not mentioned in their campaign platform one way or the other. It wasn't brought up at all by any of the parties, probably because it wasn't in the public mind then. If it had been in the public mind at the time, voters and media would have asked candidates about it.

So why does this bother people so much? Don't they realize that you can't fit every issue in the world into a campaign platform? What do they expect the government to do when an issue comes up that wasn't an issue at the time of the campaign? Just ignore it until the next election, when they can put it in a campaign platform?
