Just need to start a riff between the demonstrating factions, and all hell will break loose. These people don’t care about their cause, they just want to burn & loot.
Get the party started!
Just like Joshua and Israel. The enemy was massed against the Israelites (tens of thousands from numerous tribes). Joshua had 300 men (IIRC), had them blow their horns at three different points around the camp.
In their confusion the enemy turned against each other and the area was filled with bodies by morning, and Joshua’s men gave chase at daylight running the rest of them off.
