See, that's a problem. Drachia is a former gang enforcer who is paranoid enough not to take the word of a man who is quite possibly an assassin of the Specter that they are currently hunting seriously. It is in his nature to physically restrain said suspect to prevent them from doing anything until the Captain can show up to confirm one way or the other that you are who you claim to be... 

He is also taking the threat deadly seriously, thus the 'police brutality' to help ensure you're not in a position to try and kill us all when the idiot human lets his guard down.
