After what the government did in Waco and Ruby Ridge, killing innocent people for no good reason, there seems good reason to always be neither trustful or mistrustful of the government, but always alert.
Are those good examples to support your point? In both those cases the innocent people had an arsenal of weapons. Though I may agree the government was wrong in how they handled the situation, it does seem that the situation began due to law enforcements knowledge of a huge arsenal of weapons.
Do you possibly have examples where the government did similar actions on people without any guns? I cannot think of any here in Canada; any situations that are comparable all had guns.
