Los Angeles moved this week to dismiss nearly 66,000 marijuana convictions, years after the state voted to legalize the drug. The county is working with a not-for-profit technology organization, Code for America, to use algorithms to identify eligible cases within decades-old court documents. “The dismissal of tens of thousands of old cannabis-related convictions in Los Angeles county will bring much-needed relief to communities of color that disproportionately suffered the unjust consequences of our nation’s drug laws,” said Jackie Lacey, the LA district attorney, in a statement. Prosecutors this week asked a superior court judge to dismiss 62,000 felony cannabis convictions for cases that date back to 1961.
