I don't think the situation is bad enough to warrant violent revolt (yet).
No. We have a second amendment to maintain a "well regulated militia" to protect the state - not to make it easier to overthrow it.
The American militia were part of the revolution to overthrow the British government and the recognition of that is codified in the Second Amendment.
"Security" meant repelling foreign invaders and stopping insurrections, not starting them. To provide for calling forth the Militia to execute the Laws of the Union, suppress Insurrections and repel Invasions[4]
