How did the arresting officers know Zion didn't do something to either provoke or attack Jaylen? I mean, it "could've" been a case of Zion pushing or spitting or whatever as Jaylen was following him or he could have taken a swing at Jaylen. All we have in
the police report is Zion's testimony... one side of the story. Jaylen, according to the police report, didn't say anything. So these arresting officers on the scene have two men that were fighting. One guy drunk, not only in the wrong apartment, but at the wrong building, then when he sees Jaylen following him he calls him a "d**k" and he gets punched. The other guy, Jaylen, was in the residence (again, according to their report) and got into a scuffle with the drunk guy.
At the very least, either both get arrested, and you sort it out at the station... or neither of them is arrested. Jaylen has a bandaged hand and Zion has a jacked up grill. Both learn a lesson and life goes on. Or, you arrest the drunk smart azz intruder that called the resident a "d**k", that is obviously a danger just by him walking, much less driving if he isn't even in the correct building.
