Los Angeles – The number of cases tainted by city police evidence-planting here continues to mount, but the criminal defense bar is as much in the dark as ever about which clients are affected. Some defense lawyers are so angry about the situation that they plan to take the offensive to get the data their clients need.

The district attorney’s office says that it won’t submit evidence to defense attorneys because of its continuing investigation of an undisclosed num- ber of officers. Defense lawyers have had to learn of developments from newspaper reports.
