Occupy Oakland: Photos of violent night emerge on Twitter

As Oakland police defended their use of tear gas to disperse protesters Tuesday night, more Occupy Oakland images documenting the night's confrontations were emerging on social media.

Many protesters posted photos on Twitter -- pictures that they say show authorities' use of rubber bullets, beanbag projectiles and tear gas.

Oakland's interim police chief, Howard Jordan, justified his department's use of tear gas, but said no rubber bullets were used.

"We were in a position where we had to deploy gas in order to stop the crowd and people from pelting us with bottles and rocks," he said.

Some officers reported being hit by bottles, eggs and paintballs.

Despite dozens of arrests and a confrontation that turned ugly, organizers vowed to return Wednesday evening. "TODAY 6PM 14TH & BROADWAY #RetakeThePlaza #StandWithOakland #OccupyOakland," organizers tweeted.
