Covering up a bad shoot is stressful.
Gee, kinda proves you haven't read the testimony.
He counted them out in his hand? You mean he picked them up? Isn't that tampering?
Covering up? To later count them in front of someone not involved in the shooting? That someone having been in a group at the scene which included the supervisors.
So stated the lying agent. Take it up with him. And Compean on his original statement admitted to picking up the casings.
