What if she said "I don't know who the fk he is"... then you wouldve been fked. Does getting handcuffed mean you were arrested? Or are they not the same thing?
It's called detaining, as far as I know. And stop complaining about the cops like you would be some kind of Jesus that doesn't need to be protected from crime (not refering to you, Shame, but to others with their attitude like that). This "fuck the police" attitude is in kindergarden level.
Wrong place at the wrong time i suppose.
Otherwise just be lucky you got free
