How does sec handle a revolution?

I know the play-book is:

Step 0: Don't metagame

Step 1: Gather sec to charge cargo

Step 2: Secure cargo

Step 3: ???

Step 4: You've won!

However, revolutions are incredibly rare (I play on Wizden Vulture) so I don't have much experience handling them and what can be done if Cargo is broke and none of the bounties are readily completable?

Also, how far does the benefit of the doubt go for revs? Like, can sec only start making moves after someone from sec or command is mobbed? Can sec get cargo mindshields if they suspect revs? Where is the line drawn?
