Does the Revolver Have Footing or Gunpowder?

"The lack of any footing or gunpowder does tell me, okay, this revolver was at a distance in which that type of firearms evidence ... is not coming in contact with Albert's shirt," he says. "I'm not sure why they're putting so much weight on whether or not the fabric itself had been caught on fires." The defense is saying it's possible to shoot into a shirt or anything from just three inches without leaving a mark,. meaning he could pull the gun out and shoot himself.
