Civil rights attorney Larry Krasner ­handily won the Democratic primary in the district attorney’s race Tuesday, running on a platform of bringing sweeping change to the office, and that has made some current assistant district attorneys very concerned, according to former prosecutors and defense attorneys with knowledge of the office.

Krasner won the Democratic primary with 38 percent of the vote, winning nearly twice as many votes as the second-place candidate, Joe Khan, who ended up with 20 percent.
