Does anyone else see another inconsistancy here?!?!?! I doubt anyone can get into the mind of the shooter (nor would they want to), but walk through this with me....
Shooter wakes up and decides his mom needs to be dead and she happens to have a stockpile of weapons including the Bushmaster "assault" rifle. He shoots her several times in the head and proceeds to take his brother's ID (who supposedly hasn't seen him in over a year) and steal her car to drive to the school to go on his rampage. There's enough rage in his head to shoot his mom and go on a killing spree, but he takes the time to hide a rifle in the trunk?!?!? What would he care at this point to keep it in open view with the other guns? They said on the news that he had a bulletproof vest on, but yet took his own life? What's THAT all about? If I had to guess, the reason the rifle was in the trunk was because he couldn't fit it in the passenger seat because it was OCCUPIED.
I did see news reports immediately after the incedent where some of the parents mentioned watching someone in camo pants and a black jacket coming out of the woods, claiming "he didn't have anything to do with it" and was detained, only to be released (but not heard from again).
