He was an earwitness, but not an eyewitness. He was ducking down in his car when Tippit was shot. He didn't see the shooting.
Ducking down in his car (actually it was a truck, but anyway...) when Tippit was shot?
I have to agree with Cakebread on this one, you're full of B.S.
Benavides obviously did not "duck down" in his truck until AFTER the shots rang out.
Why else would Benavides be "ducking down"? Come on, already.
