I just watched Assaulted: Civil Rights Under Fire. The documentary is about the right to bear arms, own guns and the pros and cons of gun use and ownership. The bottom line, however, is that gun ownership and proper use of guns both are rights and guaranteed by the U. S. Constitution.
Interestingly, the documentary notes that both Stalin and Hitler banned gun ownership by citizens before committing some of the most violent and horrendous crimes against those citizens.
Gun ownership is a good thing. However, with gun ownership comes a great responsibility to know how to use the gun and when use is needed or appropriate.
