Any law that is not regularly enforced should be obliterated.
Because if the law stays, those in charge can go after criminals they don't like and let the criminals they like go free.
An example of one-sided enforcement in Utah:
A college student makes false bids on oil and gas leases because he feels those areas should be protected. He is charged with two felonies.
Hundreds of ATV riders, including politicians, knowingly demonstrate their dislike of current laws by illegally riding their ATVs off road in Kanab. The event is highly publicized.
Will they be prosecuted? Or at least fined?
The environmentalist has been charged. If the anti-environmentalists are not, despite the fact that we know exactly who they are, then there is a blatant double standard.
If you're going to punish civil disobedience, then at least be fair about it. Charge those ATV riders too.
