Can you blame her if she does? I'm a cop. I expect to get into the occasional physical altercation. Unless you're the wrestling coach most teachers aren't prepared for disgruntled parents turning the hallway into a steel cage match. I hope she goes on disability while she sues both the parent and the school district. Teachers shouldn't have to fear for their lives.

If enough teachers sue the school for this type of thing, the school will have to finally act.
But I suspect the government will figure out a way to become “sue-proof”. The only tort reform we will get is to protect the government.
