why would he try to run, draw a weapon, or threaten them over a noise complaint?
from the article we could tell that he wanted to stay on the other side of the door.
why would the police throw him out of his own house? it's like you aren't listening, we don't know what's happened yet.
here's a convenient timeline of what we know for certain
1. a noise complaint is filed
2. police arrive, confront guy
3. fight breaks out, for reasons unknown
That is literally it. let's wait to here from a few other witnesses or the police involved before we automatically decide that one party or the other is in the wrong. Was this a case of police brutality? I don't know, and neither do you.
According to the information we have so far, though, they didn't have any reason to pull him from his house in the first place. He would have had to have made an aggressive first step against the officers first in order to justify them pulling him out. So far, there has been no mentions of him making any actions to warrant that.
Correction, we don't know the reason to pull him from his house. I have some extreme doubts that 4 police officers decided at once to commit some hate crimes just for the hell of it.
