It seems like we're trying to stage battles on ground just because we don't want to concede anything to people who disagree with us.
I did an extremely small amount of fact checking. The people in the video are in fact from the University of Florida POLICE Department. The UFPD employs 89 sworn and certified law enforcement officers. That means they are authorized to carry lethal arms (but may or may not depending on department policy), can arrest people, have investigatory authorities, and depending on the state, may even serve warrents.
So, these guys are the real deal. They are authorized to use force, arrest, and detain you depending on the circumstance. They are also agents of the school, and as such can ask you to leave the premises. I can tell you that in my role working for a public school in NYC, I utilized the Public Safety officers on several occassions to remove students from the premisis. That's not an everyday occurence, but it's also in no way a remarkable one.
You can argue about whether these were appropriate decisions under the circumstance, but let's acknowledge the verifiable facts of the situation.
