"there's a tape of Dehesa site from KUSI TV.....WHO could have been seen in that tape? (Many times, for example, an arsonist sets repeated fires and then shows up in tapes on the news)...just guessing/wondering what could possibly be on the tape ."
You are absolutely correct about arsonist returning to the scene of their crime to watch and such behavioral traits, aren't just limited to arsonist.
Don't know if Feldman has found something, or someone on tape, or is just fishing, hoping to find someone, but, if he finds "Avila" lurking in the crowd, it will be well worth his effort. Avila, BTW, would be my wild guess, as to who he is looking for. JMO
Yes, Avila was my first thought when I heard about the tape. It's possible someone spotted someone in the crowd, maybe Avila, maybe someone else.
UNCANSEE2 in post 911 had some good theories too.
