AARON MATÉ: We’re at the corner of Penn and North, just a few blocks from where Freddie Gray was [arrested]. It’s one day after the uprisings left a trail of damage and a few dozen arrests. We’re here on the front line of the protest zone. There’s a large police contingent here. Behind them, some armored trucks and other vehicles. In front of the police, though, there’s another line of residents who are standing guard, and we’re going to talk to some of the people who are here.
