KEN THOMPSON

BROOKLYN DISTRICT Attorney

Ken Thompson has emerged as perhaps the leading face of criminal justice reform — even as he leads the country’s largest local prosecutorial office.

His move to effectively decriminalize marijuana possession in Brooklyn pressed Mayor de Blasio and Police Commissioner Bill Bratton to offer a citywide variation on the same policy months later.

His conviction review unit has emerged as a national model.

And the grand jury he announced Friday to probe the apparently accidental police shooting that killed Akai Gurley is being closely watched in the aftermath of the failure to indict in Eric Garner’s death.

While he’s at it, Thompson has to prosecute robberies, rapes, murders and the rest of the day-to-day crime that, even in a safer city, afflicts 2.5 million Brookynites.
