From: http://www.reddit.com/r/bayarea/comments/2yv2de/video_shoot_broken_up_by_sfpd/cpdod1s On March 8th at 5:30 pm, officers patrolling at Harbor and Northridge observed a crowd of subjects, many of whom were known Big Block gang members, congregating in the area. The officers inquired as to what was going on and were told by one of the subjects that they were getting ready to shoot a rap video. The officers left the scene but positioned themselves in an area of concealment and watched. One of the members of the group was seen producing a handgun and racking a round into the chamber. None of the subject around him appeared alarmed at the sight of the gun. The officers, along with back up units, detained the group and arrested the suspect with the weapon. The loaded .40 caliber semi automatic pistol was recovered. During a pat search of another suspect, a bag containing 12-15 rocks crack cocaine fell from his pant leg. He was arrested as well. Both suspects were booked at Bayview Station on their respective charges. The remaining subjects were identified, investigated, and released from the scene. (SFPD Case No. 150209417) ~/u/kippertie

Cops were detaining the subject in the black hooded sweatshirt mainly. The undercover officers observed him with a gun. A portion of the rest of the subjects were known by the officers to be on probation/parole which comes with being subject to detainment and searches as an alternative to spending time in prison or jail. The officers recovered the gun quickly (around the 1:36 mark "221 in custody)." The rest of the subjects who were on probation or parole were transported back to the station to make sure they had not violated the terms of their probation/parole. (Stuff like hanging out with other convicted felons). The subjects who were not on probation/parole and did not have any outstanding warrants were released on scene. I hope this answers your questions. No drama, no fuss, a felony gun arrest. Just another day in the Bayview. ~/u/_rhetoric
