Commentors here and here are pointing out this story about Dr. Fahdli. It looks like the shooting was not random and that the prosecutor was talking out of turn.

Plus, I got an e-mail from a man who knew the doctor when he was in high school with the man’s nephews. He says that Wameeth is neither a jihadist or terrorist and that his wife does not wear the burka. He also says that

the odds it was an unmotivated, impersonal, random shooting are zero.

It looks like our assumptions were wrong.
