THE PATRIOT ACT (October 24, 2001)
You should familiarize yourself with this piece of legislation. If they don't get you for something else, they may get you for this. It's all-embracing. But you might make it work for you too. It used to be for IRS infractions. Now it may well be for this. (Don't play outside with a laser beam, for example.)
