To date, 21 states have adopted laws allowing citizens to protect themselves by use of force outside their homes. This goes against the Federal law which only allows for deadly force if the perpetrator is within the confines of ones home.
There is a flaw in the state laws, which does not address the programmed psychological judgement of the arms bearer. It gives too much authority and right to untrained citizens who may live in fear on a daily basis, the right to make an assumed judgement on individuals deemed a threat to them. It allows the use of deadly force with a weapon against unarmed citizens.
The law is unconstitutional and should be addressed to protect unarmed innocent civilians from bias vigilante justice seekers.
