the police aren't there to protect, they're there to take notes.
it's up to you to protect your family, particularly when there are kids involved.
myself, personally, if someone came at my wife (female or otherwise), I would grab the first solid object and go to town. i recommend that in the future you and yours do the same.
when it comes to your safety and your life, it's better to apologize than ask for permission, imo.
has ebg taught you nothing?
ohhh... and take chuck e.'s ass to court. if they've got that kinda customer, they need appropriate security.
