What is dangerous here is that instead of a criminal trial before a jury of 12 peers, and the beyond reasonable doubt standard of proof, it is a civil matter before a magistrate, and the standard of proof is on the balance of probabilities. All it requires is someone to think a dog is dangerous, or that someone thinks a dog owner is irresponsible. It is frightening.
