Paris shooting

This from the ABC:

"There was a bus full of police. The man parked just in front of the bus and then he got out a Kalashnikov and then he shot six times," the witness said.

The thing that strikes me is the appallingly bad shooting. You surprise a bunch of fish in a barrel with an automatic rifle and you manage to kill one and injure two. How embarrassing. This is your 15 minutes of fame - your great statement of defiance to the universe - and you don't even bother to do a bit of practice first?
