They did mention that. (The whole article is at the link; I couldn't post it all.) They also mentioned that even police departments have reported numerous accidental discharges of this particular gun.
Yes, they did mention it and then questioned the safety of a gun with a 10 lb DA trigger pull. Ridiculous!
They did fail to say that the judge would not allow the jury to hear or see any evidence or testimony about the operation/characteristics of the gun.
Again; all of that is irrelevant to my point. All guns fire by pulling the trigger, have for over 700 years. What child of five is unfamiliar with that concept?
