I'm sure there are; just as there are misuses of firearms. However, both are morally-neutral tools that are reasonable in terms of their possession. I would fight the misuse of this law, not its existence.
Me too, I was addressing the fact that you hadn't heard of any cases of abuse. I know lots of them. Quite a few from personal experience.
They chill your blood unless you are already understanding that all laws will be misused sooner or later. It's human nature. It's one reason we need fewer laws and better enforcement of the ones which violate rights.
