Opinion: Tea Party's Rand Paul Correct, Laser-Pointer Law Absurd - TIME
That is a VERY important question... how is the law enforced? One way to enforce a law is to identify situations where it has been broken, and then catch the perpetrator. The other way to enforce the law is to choose a person to prosecute, and them watch him until he commits a crime. In a country where the vast majority of crimes are never prosecuted, and the "criminals" often don't know that they are breaking the law, it won't be to hard to follow the later strategy.
It takes only about five seconds of thought to see that Rhode Island Senator Sheldon Whitehouse's amendment to impose federal penalties — up to a five-year prison sentence — for [aiming a laser pointer at a plane] would be completely useless. How exactly would it be enforced?
