Dallas Police Chief: Shooter Scrawled in Blood

"At the scene where (Micah Johnson) was killed, he wrote some lettering in blood on the wall," Dallas Police Chief David Brown tells CNN in an interview Sunday. "Which leads us to believe that he was wounded on the way up." Brown says that Johnson scrawled the letters "RB" in his own blood, and that investigators are trying to decipher the significance of that. Other highlights from Brown's wide-ranging interview, via Politico, the Hill, and the AP:

• On the five-hour standoff with Johnson: "He just basically lied to us, playing games, laughing at us, singing, asking how many did he get and that he wanted to kill some more and that there were bombs there so there was no progress on the negotiation. And I began to feel that it was only at a split second he would charge us and take out many more before we would kill him."

• On his decision to use a robot to take out Johnson: After telling his officers to use "your creativeness to come up with a plan" to end the standoff, they came back with "a device to detonate behind the corner within a few feet of where he was that would take him out. And I approved it. And I'll do it again if presented with the same circumstances."
• On critics of that decision: "I just don't give any quarter to critics who ask these types of questions from the comforts and safety away from the incident. So, you know, that's not worth my time to debate at this point. We believe that we saved lives by making this decision. And you know, again, I appreciate critics, but they're not on the ground and their lives are not being put at risk by debating what tactics to take. And I'll leave that to them for a later discussion."
