That would be awful. But saying it happens does not mean it happens. (no offense)
And as for apocryphal (sp?) stories like this, I can come up with several too. Oh wait, I am living one!
Since there's a chance stories like this ARE true (which seems likely given that you have similar stories of your own), doesn't it make sense to reform the system... just to be on the safe side?
For example, how about giving all sides equal access to legal assistance? Or requiring some form of proof to substantiate abuse claims, or perhaps giving each side a chance to defend themselves in court before imposing something as serious as a restraining order, etc?
