The FL state firearms expert that just got done testifying should have the jurors thoroughly confused about the Kel-Tec PF9 by now. Both Guy (prosecutor) and O'Mara are partially responsible for that, but O'Mara especially asked a series of questions about "trigger pull" as it relates to amount of force in lbs. it takes to fire the weapon, and interchanged those questions with "length of travel" questions in relation to how a double-action-only weapon needs to have the trigger pulled for it's full length of travel for each shot fired. So the point he was trying to make was that the PF9 requires a full-pull for every shot, as opposed to a SA whose trigger break is much shorter. He never made that point though, and the "expert" never corrected him when he said that, instead of the length of pull being significantly different in SA configuration, the force required to fire a SA is significantly lower. That simply isn't true, at least not unless the weapon has had a trigger job performed on it.
I have no clue why this "expert" was even necessary. Both sides should've been able to stipulate to how the weapon operates and that it was indeed the weapon that blew the holes in the pieces of clothing she tested. All her testimony could conceivably do is confuse the jury on how a DA-only vs. SA trigger mechanism works, and that confusion could lead to the jury thinking that it takes less effort to fire the PF9 than it does, say, a 1911 or whatever.
Bottom line: At least with this witness, every person in the court room involved in any discussions while she was on the stand, including the "expert" herself, to the judge to the prosecutor to the defense attorney, are total idiots when it comes to DA-only firearms. Everybody would have appeared much smarter to people who know about firearms if they'd have just stipulated to what she was there to testify about. That being, the gun was a PF9, it was in good working order, it fired the bullet that made the holes in the two garments she tested and was in contact with the top layer, and that's it, thank you and have a nice life. You're excused!
