From Copwatch@Occupy Oakland:
Beware of Police Infiltrators and Provocateurs
Either these Oakland PD officers are:
1. agent provocateurs
3. have decided to join Occupy Oakland in their spare time.

As for the use of tear gas, it was inadvertently revealed that OPD was considering gassing the occupation when a conversation was overhead between a not-too-subtle undercover officer and two other people at the Occupy Oakland General Assembly on October 20th, the evening that the city of Oakland first distributed a notice to vacate the occupation at Oscar Grant Plaza. While certainly OPD and other agencies interested in the occupation have undercover officers and/or informants that may not stand out so much, during this General Assembly it was obvious that at least a dozen undercover or plainclothes officers were present gathering information that could be used later should a raid of the camp(s) be ordered. The undercover who revealed the intention to gas the occupation first asked the two people sitting on the amphitheater level in front of him about something he had heard a speaker say from the microphone. The speaker had offered information that Maalox and similar substances can be useful to treat the burning effect of pepper spray to the eyes if such a chemical weapon should be deployed by police. The undercover asked the two people in front of him if the Maalox was something that occupiers planned to squirt into police officers' eyes. They explained that what the speaker had actually said was about a treatment for pepper spray for protesters. The undercover then went on to ask the two people if they knew anyone who had gas masks, adding that he knew someone who had some masks. It was apparent that the undercover was gauging occupier defensive capabilities. The two people said they did not, but the undercover certainly does know people with gas masks. All of the invading OPD officers donned gas masks after their first volley of the chemical weapon into the camp blew back into their faces due to the direction of the slight breeze at the time.
That night, police raided Occupy Oakland's camp, arresting protesters and using tear gas.
