The fact that law enforcement would be silent isn’t shocking ... that would be expected ...
it’s that the media hasn’t gotten any wiff of anything from any of the students that knew/knows the girlfriend. Law enforcement couldn’t keep these kids under lock and key ... and we know the media is getting alot of talk from students.
That’s the source I’d expect, the friends or classmates of the girl in question.
Here’s something else that’s weird. Assuming that the shooter has been killed, there’s no “legal case” to be made here. Why be so stingy on details?
Does anyone remember how long it was after Columbine that Harris and Klebold’s names were released?
Give it time. Remember there are something like 22,000 students at VA Tech. Sooner or later someone who knew the shooter and/or girlfriend will show up.
With no ID yet on the shooter, and the President getting ready to speak on the event, that may suggest this was some type of terrorist action. I don't know, just speculating like most others.
But the fact remains, no ID on the shooter, hours later, after the event, is rather odd.
