A few of the protesters spontaneously broke off from the main group and vandalized cars in the parking lot, a guard shack, slashed the tires on a government van and broke a security camera. When a police officer arrived on the scene and drew his weapon, one of the activists fired an AR-15 from the woods, hitting the officer in the shoulder. The officer survived.
So, more than signs & chants, and way less than ICE agents murdering and breaking into homes without warrants. On the whole, the protesters sound like they were on the side of justice combatting government that's operating outside the law.
