Intentional or not "calling the shots" was a good line.
This whole situation is a concern. That building seems hugely obvious as a shooter's location. How could he have been up there for minutes - long enough to extricate the gun from his backpack, assemble it, and start shooting - before they were able to get shots at him? How could a significant portion of that building be completely uncovered by counter snipers?
Thinking about the Kennedy assassination, Reagan's shooting, and this incident, it makes you realize how easy it is to assassinate a president. It's surprising it doesn't happen more. I'm frankly amazed that Obama wasn't assassinated, knowing what we know about the prevalence of racism in America.
