So there's 3 agents:
1. Government. Trustworthy, until it isnt.
2. "Union" - Trusts govt. Ok with "gun grabbing" because civians with guns make them feel safe.
3. "Rebels". doesn't trust government. Ok with guns - armed society is polite society.
So it's a very unstable dynamic. It's stable at the extreme ends - everybody has guns, or only government has guns - but the transitions are high activation energy states.
