"what policy states that they have to be in uniform even during off duty hours?"

The cops were not off duty. They were there on duty and undercover.

"If you guys feel it was ordered that they be there where is that proof?"

Lt. Rudy Escalante of the Santa Cruz Police Department was quoted in the Santa Cruz Sentinel on 12/31/05 defending SCPD infiltration of public meetings. Escalante states, "If it's a public meeting about a public event on a public thoroughfare, we'll be there."

"The police have civilian lives so it not unreasonable for them to show up to a public event."

They were at the meetings as undercover police officers and they were getting paid for it.
