Ha! Jersey is like being in a prison or a farm without any proper self defense. No matter if you're in the country and a deer attacks or you're in jersey city or Trenton and a deer attacks....you still cannot defend yourself.It's neither common nor enforceable. It's preempted by State law. San Antonio has a lot like Jersey City, NJ -- it thinks it's not subject to state law.
P.S. there are no deer in Trenton or Jersey City, or Newark.
