I'll assume you live in the US: doesn't your constitution grant you the rights to bear arms and didn't one of the founder said it's the people's duty to throw away the government when it gets corrupted ?

On a more "scholar" note there is the notion that a leviathan is needed.

Moreover, I think private companies and individuals can be as violent, or more, than any government that claim monopoly on its use.

Be it physically or symbolically.
