It may appear he was trying to make an arrest, but the question is for what?
That's not a question for you or I or any other civilian on the scene to decide, at all.
And why did he not tell the girl she was under arrest prior to using force?
How do you know he didn't? You don't. Furthermore, in the second video early on I hear someone saying "arrest."
By all reports, this did not happen the cop just started to use force against the black girl. Also, was it a lawful arrest?
By what reports? Link with proof, please.
I'm sorry, being loud is not a crime.
No, but being ordered to leave an establishment by a uniformed officer at the behest of the owner and then refusing and then physically resisting being forced to leave is.
Maybe that officer could have better handled several aspects of this incident, I don't know
and neither do you.
Maybe he IS a dick, I don't know. But he did nothing wrong in either video that I saw.
You don't get to disobey an officer.
You don't get to interfere with an officer in the act of carrying out his duties, and you SURE don't get to put your hands on him in any way, shape or form.
You don't get to physically assault an officer, and that officer has every right to use force to counter your assault.
You don't get to be as boisterously loud as you damn well please in an establishment, and if you are asked to leave, you must leave.
If you refuse to leave, you may then be "escorted" from the premises.
If you physically resist leaving, an officer may use force to compel you to leave.
If you resist this, that officer may then place you under arrest.
If you resist arrest, force may be used to place you under arrest.
The one cop may or may not be a dick in real life, but both of those women were in the wrong from the get-go, from what I saw on those two videos.
