The little loser probably tried it so he could be famous (albeit post-mortem) as the guy that did it.
And he could have “reconnoitered” the scene from the comfort of his own room by using Google Earth.
But how did he know which roof would be unguarded?
The total lack of emotion in his life and in his actions on Saturday, as portrayed, gives me the feeling that he was acting like a robot.
They’re looking for any signs of radicalization etc but either they are removing what was there (like they removed his social media which they acknowledge existed) and creating a totally different person, or the kid was a blank slate and robotic.
If he was robotic as they present him to be - so normal, nice, well-adjusted, and no contacts or points for radicalization - it suggests mind control, to me. He didn’t have anger, didn’t have opinions, didn’t have motives. Yet he mechanically did it. The weirdness of it should raise eyebrows.
