My question involves civil rights in the State of: New York and the U.S.A.

The following questions are totally hypotheticals. Nobody is going to act on the answers. So please do not be alarmed. Thank you.

1. If someone steals a lot of money from people and they can prove it do they have the right to bear arms to kill the thief under the 2nd Amendment?

2. If the Courts do not provide a person with an unbiased proceeding does this person have the right to bear arms or form a militia to kill people to make things right?
