What does that kind of prosecution say about an Attorney General who allows it to proceed?
Carrying a small knife is legal. Brandishing a weapon is not, but if one is placed in reasonable fear for one's safety (in respect of time, place, and situation) a preparatory motion such as this man made does not seem to rise to the standard of "threatening". He had no way of knowing that his pursuers were police officers, and once their identity was established, even they agreed he was cooperative. Bad decision all around.
