Were you there?
Couple of people I know are young NYPD foot patrol officers. They LOVE this assignment, most overtime they’ve ever had... even though it’s the smallest protest they ever were assigned to patrol/guard. The OWS crowd has been overall non-violent to those not involved in the drama.
That area when not hosting a protest is probably the safest area on NYC, Zuccotti Park turned into a gilded cage as soon as NYPD got a grasp of the protest.
