You have no idea WHAT she was stealing, so don't assume what it was!
You can't "talk to" a kid who is running away, nor one who is hitting/punching, whatever else she was doing to the cop/s!
You don't have any kids do you.
Just like we learned after all the idiot police chases, sometimes it is best to let them go.
I currently teach middle schoolers in NYC. If you're a police officer, handling any one of them would be a joke. The school has a small NYPD guard (maybe 150lbs) who routinely gets into brawls with 4+ kids, no problem and no need for even a nightstick.
