^Which is what the show wants to establish. The idea that the militia bring order and peace of a sort. As they flashback in future episodes to Miles and Monroe forming the militia that will become even more clear.
The sad part is the militia would be the good guys, if they didn't act like thugs. And they don't need to be thugs, except that they are written that way because the show needs bad guys. The writers of Revolution need to establish soon why the militia is bad in principle, other than just their actions.
