made a huge mistake by threatening us and trying to pushous out. and if they act on that, they will regret it. reporter: in oakland, both protestors and officers were injured. they shot flash-bangs into the crowd. reporter: mayor says that she doesn t want that here but that people can t live in the inner harbor. this is about a campout. and mceldon square and our public space are not there for that reason. reporter: when pressed, the mayor gave no clear time line. mceldon square is a desmate designated protest area. many say they re willing to get arrested. my at the point is overthere. it s green, shiny. but yeah, most of us are prepared to go to jail because we don t think anything bad will happen from it. how long will you get a misdemeanor charge? how long will you go to central booking? reporter: as the police chopper flew overhead, the people here seemed unconcerned. the city said it is still willing to negotiate for a peaceful resolution. reporte
