Maybe it was the distortion through the window, but the man I saw in the window looked pretty old for a terrorist, FWIW.
I heard the guy outside, who was bumped describe him as middle aged...and someone said there were 2 others were with him, so maybe they did not go inside, or actually were not with him.
The texting hostage said be careful, and the vest issue came up, so something seems up. I guess time will tell.
