Great report PhiKapMom. Couldn't you just guess that OU authorities would put out the info that Hinrichs wasn't seen on any video surveillance cameras. Duh, maybe they just forgot to mention that there weren't any video surveillance cameras.
Only old ones I saw were pointed toward the back of the ticket booths so technically they could say they had them -- just didn't point them toward the gates!
Note that the video cameras didn't pick up Joel exploding himself, either. Doesn't mean it didn't happen.
