Because you're a law enforcement officer, and it's the law?
Sure, it's a dumb law, but if you choose a career as a LEO you're not signing up to decide what the laws are. That's the legislature's job. Your job is to enforce the dumb ones along with the smart ones.
It's like the scene at the end of The Untouchables, after we've watched Eliot Ness throw everything he has into fighting bootleggers for two hours. Someone runs up to him waving a newspaper announcing that Prohibition has been repealed and asks him what he's going to do now. And he looks at the paper and replies "I'm going to have a drink."
