I don't think I made myself clear, although some of the other guys have picked up on it....
Generally, a good shoot is a good shoot from a criminal standpoint. Really doesn't matter if the gun has been modified beyond all recognition, or you just put some white paint on the sights.
There are Prosecutors out there who'd like to hang us for that sort of thing, but it's rare, and usually the result of inept defense.
However, should a shooting get into Civil Court (they don't all do that), the other guy's Attorney will try to go after you for
anything he thinks he can get away with. Your Lawyer should be able to deflect most of it, but it can still poison the minds of some jurors. Deeper pockets make this sort of thing more likely.
Which is why Mas is primarily talking to LEO's as many of them would be covered by their employer. "Scalping" an LEO who's not so covered may also be on the other guy's list....
Finally a story.... A friend of mine was called as an expert witness in a murder trial. (She's more than qualified, IMHO, and was accepted as such by both sides.) The Defendant's lawyer (and the Defendant) claimed that he couldn't have shot the Deceased because his gun had a broken firing pin, and didn't work....
Marlene looked over the gun, and then asked the Bailiff for a pencil. She cocked the gun (1911), pointed the barrel towards the ceiling, and put the pencil in the barrel. She fired, and the pencil headed upwards nicely.... So much for that defense.
