subway arrest

back story... This went on for about an 25 minutes early Saturday morning. I am mad i didn't get most of it but i did not think it would go on for so long. The lady ( who i at first believed was a guy) was either begging for money and/or running that metro card scam i didn't know which one exactly because the cop kept going back and forth. He reached his point when a man handed the lady 5 dollars and the lady said " i will put this on a card (metro)" as soon as she said that he slapped cuffs on her... at the least i was confused
The cop kept taunting her telling her she wasn't screaming loud enough, telling her to scream louder. She started crying and begging for him to not arrest her. It was sad
