Man violently assaulted in front of indifferent onlookers in Oakland (Warning - shocking)

A shocking video recently surfaced showing a man being violently assaulted by several individuals at an event in Oakland. The footage shows the bloodied victim lying on the sidewalk, seemingly unconscious, as the attackers continue to beat him. What's even more shocking is that the crowd of onlookers watching the scene seemed indifferent to the man's agony, some even taking video of the violence without intervening. The attack was preceded by an altercation between the man and a car doing stunts, but that in no way justifies the extreme brutality of the attackers' response. Oakland police are investigating the incident, but the victim's condition remains unknown.
