While I won't minimize the concerns, I have to say that this sounds like more of a "prank" than serious terrorist activity. Without going into gory details, I can say that the explosion of a conventional flashlight full of RDX or TNT or even black powder would have had much worse results than "minor injuries".
I do hope the police and federal officers find the guy and lock him up for a long time; if he gets a short sentence he will consider it part of the learning curve and resolve to do better the next time.
