Have they confirmed that he really filed off the serials on the 9mm yet? That always seems odd, although I suppose he had planned to go columbine at some point and planned ahead like that.
The videos do seem to be over quite some period of time. I’m sure the files themselves will have their record dates and so on still.
The videos were made in different places and yes, they confirmed that they were made over a period of six days.
He was insane and should never have been made an outpatient.
And I also don't understand why the college didn't boot him out, after all of the problems he caused in '05.
