Your opponent gets to vote in battle, anon. If we had the ability to simply throw all the bad guys in jail and prosecute them in court, then they wouldn't be as embedded as they are in that very system of justice, now would they?
What is your alternative, anon? To… What - take up arms and start eliminating people based on who we think is guilty?
You argue that we don't seem to be winning - but this deflects from the fact that we aren't really losing, either. Sure - the enemy is doing a thing, but are they really causing as much damage as they need to in order to win?
No.
These are actually not resulting in the kind if citizen-on-citizen hostilities necessary to trigger a collapse.
