Which Laws Would You Like to See Selectively Enforced?

Whether it's outgoing presidents giving pardons for crimes they might not see as being as severe as the convicting jury obviously did, or ideological things like immigration or marijuana possession, many don't agree with some of the current laws on the books. There are also instances where people might agree with the law, but feel that the way it is enforced is excessive and can make a criminal out of someone who isn't necessarily one. There have been people arrested for what started out as simply failing to return a library book.

So if it was up to you, which laws which you like to see more selectively enforced?
