If the camera technology is available, why not use it in the hopes of catching something?
They caught a squirrel in what they hoped was a bear trap, maybe? It shows the investigators are looking at everything they can.
I saw a red Dodge type car stalled on the side of the road in North GA this morning on the other side of I75 around Ringgold (I was going south, so the car was on the shoulder on the north side of the fast moving interstate next to the concrete dividers between the north bound and south bound lanes). It had big white stripes down the hood. The trunk was open. Traffic moves so fast on the Interstate, and there were no police involved. I kept going, but did think about this forum and wonder if I should have turned around. Like all of you, this case, and others like it, can make you chase phantoms, and I probably would have looked like a big idiot had I done so.
I guess we need to let the investigators do their job and hope for the best.
