The correct response should've been "no" and walking on.

Avoid the government. Especially the ones in uniform. No good will come of it, I'm telling you.

wcbstv.com - Would-Be Samaritan Instead Busted By Police:

"A New Jersey woman trying to be a Good Samaritan was instead busted by police. And the whole troubling incident was caught on tape.

Monica Montoya, 25, happened to be walking by the scene of an accident in Roselle Park, N.J., when police asked her if she spoke Spanish and could help interpret for a woman who had just been struck by a van. Montoya tells CBS 2 News that she agreed to help, but moments later, the 25-year-old's attorney says his client was bullied by police and placed under arrest.

Police, however, claim Montoya was being uncooperative, so they cuffed her and put her in a squad car."
