WJZ’s Marcus Washington was able to meet and speak with gang members of the Bloods and Crips together.

“United is key. You’ve got to be a collective whole to try to sit there and make something happen. Just one can’t do it. Us being together is a better outlook in the whole situation,” one member said, wearing an “I Bleed Baltimore” t-shirt.

The groups say they are at the rally for peace and not to condone violence against police.

“We’re not here to do nothing to the police, we made that clear countless times. We try to embed that in everyone’s mind. If that was the case we wouldn’t be here right now,” he went on to say.
