The infiltration took place as the city itself faced restrictions on using its own officers for such undercover operations under a long-standing mayoral directive.
The infiltration continued to draw sharp criticism yesterday from the state chapter of the American Civil Liberties Union as well as from participants in the demonstrations.
Stefan Presser, the Pennsylvania ACLU's legal director, said the use of state police undercover agents was "an end-run around the mayoral directive. Through the state police, they accomplished indirectly what they couldn't accomplish directly."
The directive became binding on city police in 1987, after the ACLU and other groups filed a federal lawsuit challenging the Police Department's infiltration of leftist groups planning to protest during the celebration of the 200th anniversary of the U.S. Constitution.
The directive says the city police cannot infiltrate protest groups without the permission of the mayor, the managing director, and the police commissioner. This requirement, say the civil-liberties lawyers who pushed for it, was designed to ensure accountability when police go undercover against protest groups.
While Mayor Street and Police Commissioner John F. Timoney continued yesterday to refuse comment on the state's undercover operation, it was enthusiastically endorsed by Gov. Ridge.
Ridge's spokesman, Tim Reeves, called the state police action "a basic step to ensure public safety in the face of a clear threat." Lewis said the undercover work was appropriate to "our primary role at the convention, which was providing protection for governors in attendance."
During the convention, Timoney repeatedly denied that police had engaged in infiltration.
At a news conference yesterday afternoon, representatives from various protest groups, along with the city public defender's office and members of the ACLU, denounced the contents of search-warrant documents made public Wednesday.
The documents were the first public acknowledgement that police had infiltrated groups planning to protest during the Republican National Convention.
The documents were part of the probable-cause affidavits for search warrants for three vehicles and a warehouse at 4100 Haverford Ave. in West Philadelphia, where more than 100 puppets and a large float were being built.
Jessica Mammarella, who was arrested inside the warehouse Aug. 1 along with 75 others, said yesterday that the protesters inside knew there were undercover police among them.
"We're a movement trying to build, and we didn't think we should exclude people," Mammarella said.
"Those people were involved in almost every process of what we did. We're a little bit upset about that. There was a trust thing there. I feel very betrayed."
Mike Morrill, organizer of the Unity 2000 march held the Sunday before the convention began July 31, said his group was cited in the search warrant, even though it had a legal permit to march.
"Unity 2000, from the beginning, was a legal action. We did everything according to their rules. Yet from Day 1, we were still investigated and harassed."
The protesters say they are also concerned about the return of their property seized in the warehouse raid.
Attorney Andrew F. Erba has written several letters to the city's Risk Management Division requesting the return of the property. The city's response, he said, has been unsatisfactory.
"Generally, they don't come in and take all your property," Erba said. "What's unusual about this is, they went into the warehouse after all the kids were taken out, and they took all the property and took it away."
Morgan Fitzpatrick Andrews, 29, who lives in West Philadelphia, was not arrested during the raid. He was putting on a puppet show with his Shoddy Puppet Company the afternoon of the raid. He said he lost six pairs of scissors, a drill, two hammers, two saws, staple pliers, and other tools that were in the warehouse when it was raided.
"I went to Risk Management. I went to L&I," Andrews said. "After getting this claims form, I was told that my stuff was in the seventh floor of City Hall in the evidence room. They said, 'That's being held for evidence.' "
