Usually they are keeping the peace at someone else's protest.
But this Saturday, the cops are protesting:
"On Saturday March 9th we are organizing an “informational protest” in the City of Rye. We are inviting you, your family and friends to please come support us. Our message that day is to communicate to the Rye public of our difficulties in reaching an amicable contract resolution for over 4 years. We will be meeting at 17 Elm place in the center of Rye’s business district at 10am, the event is scheduled to run until 2pm. With your help and support we can successfully deliver our message to the Rye taxpayers and ultimately to city hall, the mayor and the city council. For more information please go to our website RYEPBA.ORG or call the number below.
