The professor offers no opinion on whether:
- Auto makers should be liable for car accidents
- Weathermen should be liable for flood damages
- Law professors should be liable for frivolous lawsuits.
Personally, I'm willing to print him out a dozen or so "Owner Unarmed - Pleaser Don't Rob Me" signs he can put in the the windows of his home, car, or tape to his shirt. Then he can be responsible for (and liable for) his own damn safety.
