"Nov. 5, 2010: in the killing of Oscar Grant. OPD unlawfully arrests approximately 150 demonstrators." Is there a typo in there?
Also, on January 28th, it was over 400 arrests, not an even 400.
Lastly, this omits another dimension of this mess: repeated mistreatment of jailed protesters by the Alameda County Sheriff's Deputies who run the jails.
