Initially his defenders here and elsewhere were postulating the popcorn defense but abandoned that rather quickly.
With the UFO defense his attorney is somehow alleging that the victim had three hands — one for his cell phone, one for the bag of popcorn that he threw, and a third arm for that UFO that he threw.
Perhaps he is going to allege that the victim himself was an three-armed Alien — just before he files the insanity defense.
If this guy has half a brain, he’ll plead out.
I'm quite sure he'll eventually go for insanity, but it won't help, even though the guy obviously had ... issues.
