i'm wondering how many more of these we'll see in the coming months. larry johnson has ongoing thoughts about all of this;

I will be updating this during the next several hours. Here was my initial reaction. It sounded like a 22 caliber, but it could have been larger, such as a .223 or .556.

The big take away is that Secret Service failed to fully secure the perimeter outside the venue. The shooter was killed by counter-sniper fire...........more.......
