Many of us here feel similarly - and direct our anger at LE. But it's a double-edged blade. On the one hand, we're frustrated (I refuse to say it the way HE does) at the lack of information we're getting that might enable us to protect ourselves and those we love. But on the other hand, everything he says seems to wind up becoming a part of the shooter's MO. So we waver between wanting to know everything and wishing that Moose would just shut up altogether until this is resolved. The anger, though, is quite present. I think it's general anger, though, at the feeling of being utterly unable to control something that, like it or not, is affecting our daily lives - and anger flourishes best when it has a specific target. Moose is an easy one.
My one opinion is that the sniper is a man who works nights. He operates either at night or early in the morning. He must have staked out the area near where he hit this morning, and lives or works nearby and knows that this bus stops there every morning for a while. My guess is he goes home every day and acts like nothing has happened. Either that, or he knows someone who works nights and owns a van that he can "borrow" without arousing any suspicion. There have been so many shootings in this area of Maryland that it seems clear he knows this area very well. The other Virginia shootings have been in places very close to major highways.
