NEW: U.S. Attorney Jeanine Pirro draws a hard line against teen lawlessness following a violent brawl at a DC Chipotle: "It was a takeover of a restaurant by individuals who felt they could get away with it. Well, they're not going to get away with it." "The message that lawlessness runs the streets is over." "The city belongs to law-abiding residents, not roaming mobs looking to make a name for themselves, contribute to the chaos and violence, or gain social media attention." "These are not kids being kids."
