First, the law is not science.
Second, if it happened once, it can happen again. Since this is based in secrecy, we really don't know if it's the only one. It's the only one that's gotten publicity. That much is sure. There are many people in this country who don't have anyone to stick up for them. A lot of them are street people. Who is going to go to bat for them if they're caught in a web like this? Or are they less valuable, and therefore expendible?
Third, bad law is that which erodes values upon which a society is based. This is bad law.
