Retired LEO here. Most people do not realize that the attorneys don't take an oath to tell the truth during a trial. All they have to do is implant a suggestion that sticks with one of the jurors bias. So they can say anything, get it objected to, but the damage is done. If you should ever have the misfortune of being involved in a shooting, if your not charged criminally, you almost certainly will be sued. Either one is life-changing and expensive. I've been retired 13 years, and a jury trial back in my day with a decent attorney defending you in a homicide was 500K in SE Virginia. I still CC and my ammo is what I carried when it was issued to me, 9mm Golddot, 124 grain +P.
And by the way, LEOS don't take an oath to tell the truth either, too many cases of investigators and interrogators lying to suspects to get them to admit something, it is rampant.
