I have no idea how much suffering has been caused by people reacting to a genuine tragedy by saying, 'There oughtta be a law!' We already have laws. We have too many laws, in fact. And at some point we have to accept the fact that no law can ever stop human beings from hurting each other.
In this culture, when bad things happen, we immediately leap into action to try to prevent something that already occurred. There's a phrase for this: Locking the barn door after the horses are gone. We have gotten very good at this. When a child dies and the media turns it into mass entertainment, usually someone will propose a law named after the victim. But laws have far-reaching consequences. There are always circumstances where even the most well-written law will end up hurting an innocent person. In the case of Caylee's Law, what is proposed is that parents must notify the police 24 hours after a child goes missing, or one hour after a child dies, or it's a felony. It's not hard to see how this could lead to grieving parents being put on trial because they cried a little too long over their child's body.
There's other reasons to oppose this law. But most of all because it's the kind of dangerous stupidity that we already have too much of. If it had been in place before Caylee's death, it would not have helped her in the slightest. And it won't help anyone else if it's enacted. All it will do is imprison the innocent and add a bit more punishment to the guilty. That's all this is really about. Punishment. A lot of people feel cheated that Casey was found not guilty, so they hunger for the catharsis of seeing someone punished. It doesn't matter who.
Laws need to be based on more than just sounding good to our gut feelings.
(BTW, I am not at all interested in discussing whether Casey's guilty or innocent. I can't possibly know, so I don't care.)
