I also think it's very telling that he attacked someone on a bus. He's already managed to shut down the schools, empty out shopping centers. Is he sending a message that commuters are next? Is he trying to frighten the public so they'll be afraid to venture out to work on buses and trains? Afraid to leave their children? I keep thinking about that tarot card that surfaced in the arab newspaper last week -- the one with the words "curfew" written out in bullets.
Huh???
I wonder... based on conjecture that the sniper has directly threatened children, presumably schoolchildren, if his bus shooting today was to show that buses, including schoolbuses, are unsafe. Many parents are already staying with their children at bus stops, if not driving them directly to school - but if the sniper is trying to show us that he can shoot when people (including children) are ON THE BUSES...
I'm probably overthinking this, but I have this disease where I have to post every single theory I come up with.
