In PA we have the Stand Your Ground law which states:
A person in any lawful place outside his home “has no duty to retreat and has the right to stand his ground and use force, including deadly force if . . . (he) believes it is immediately necessary to do so to protect himself against death, serious bodily injury, kidnapping, or sexual intercourse by force or threat.” (18 PA consolidated statutes 505(b)(2.3)).
Now stand this statement up against a bullhorn in your ear at one of the many increasing protests that accost innocent people sitting outside and eating dinner on public streets. A mob will come by, stop at the restaurant, and demand you raise your fist to support the BLM movement. If you don’t raise your fist, the mob will surround you and scream into your face with bullhorns.
Bullhorns at close range will cause permanent damage to your hearing. I consider the ability to hear as a major function of the body. If someone willfully blasts a bullhorn in your ear, does that consitute “serious bodily harm” and therefore allow you defend yourself with lethal force? At the very least it should support brandishing of your weapon.
