So many mysteries.
It's 24 hours later and-
1) Only 1 known pic of a guy living on planet Earth for 64 years and his eyes are closed?
2) No specific details about the weapons?
3) No video footage from the hotel in the most surveilled city in the world?
4) No hints to ANY possible motives?
5) Why does this guy seem like he has military training?
Maybe the government is actually doing a good job investigating while not leaking stuff to the press?
Or maybe it's an inside job he was a cia operative and you have to go through the body list to find your motive.
Maybe he wasn't the actual shooter at all and the shooter is on the loose still... That'd explain why the pro shot for 15 min, then killed this old dude, and left the scene well before cops ever showed up.
