 With the big fireworks event scheduled for Uptown on July 4th, CMPD Chief Johnny Jennings said he and his staff are using preventative measures to try and ensure that what happened last year with scores of teens being arrested, as well as the mass shooting on New Year's Eve, doesn't happen for a third time. Jennings said during a press conference with the Charlotte City Partners that CMPD has started an initiative called Jade.
