San Francisco Public Defender Jeff Adachi is the one making the claims, along with a list of private lawyers who represent the people who claim their were victimized by police.
Adachi has released a total of four video surveillance tapes that he says show officers violating suspects' constitutional rights during busts at residential hotels around Christmastime.
"We have examined the pending cases and based on the information known to date, we cannot proceed with the prosecution of 57 cases at this time. Fifteen of these cases have already been dismissed. The remainder will be calendared and dismissed today," Gason said Wednesday. He added that the felony cases could be refiled if there was a change in circumstances.
