I don't blame you but I'd be very nervous if my government has the power to confiscate all guns from so-called 坏人或精神病. If the government is this powerful, how can anyone stop it from being a tyranny?

In human history, governments killed far more innocent people than gangsters. Ordinary citizen with a gun has a chance against criminals, but little chance against a tyrant government.

I'd rather face a criminal than a tyranny.
