I heard this, breaking, on KFI this afternoon....so (thankfully) it was a hoax...?
The bomb was a hoax, but the set-up, attention from the police, the crowd and media was not a hoax. The creep set up an elaborate fake device with wires and heavy metal components in a bag. Was it a test run or something akin to "the boy who cried Wolf." I wonder if he's pleased by the results.
What's worrisome is that one news account said that the creep would probably be charged. Probably??
