This incident on Kingston and Crown seems like it was handled pretty well

Merchants, residents, Shomrim and the NYPD all seem to have come together in a calm, thoughtful manner.

Everyone but the perpetrator that is..

As per the account, he was not in the role of "handling" the incident. He was in the role of causing it.

I accept the account.

There is now video:
