Unfortunate, and surprising, that a 100-man department in this day & age is so indifferent to legal liabilities & so far behind the times in requiring officers to buy their own guns & ammunition, with such a lack of policy & procedures in place.
Also that all involved were not swabbed.
Allowing a variety of different privately-owned weapons with no standardization is not a problem; many departments will both issue "company-owned" guns and allow individual officers to buy their own (from an approved list) if they choose.
I chose to buy my own, but they had to be approved.
And, regardless of my deliberate choice to risk clouding up a shooting if & when by violating them, there were clear written policies at my PD requiring us to carry with full load-up, and to use nothing but issued ammunition (that part I did comply with
).
In my case, I fully understood that my policy violation put me subject to certain liabilities, which put the responsibility on me.
In that one very limited-scope area, I assumed that risk.
(In no way am I advocating anybody else should do this, incidentally.)
In the case of a department with no written policy, when certain issues about an officer deviating from an "un-official" norm may arise, it CAN put the whammy back on that department's shoulders.
Case law has ruled that "Well, we all knew we weren't supposed to do what this officer did" is not enough without it being something more than mere common practice, and officers have been reinstated entirely because that "everybody just knew" wasn't a written policy.
The problems illustrated here so far are a lack of written policy regarding exactly what ammunition must be carried, and how the handgun (and other duty weapons) must be carried.
Many questions & side issues can be avoided up front with such policies in place.
A department that size should be more on the ball.
And they dropped that ball severely in not swabbing EVERYBODY.
As far as your buddy swearing he only fired once goes-
If the suspect was struck more than once (by full-weight intact bullets & not secondary projectiles such as fragments of bullet or glass caused by one or more bullets perforating window or car door sheet metal), then obviously SOMEBODY fired more than one bullet.
Swabbing could have eliminated everybody else there with a gun, right out the gate.
If no other officers fired, and it is confirmed that MORE THAN ONE BULLET STRUCK THE SUSPECT, Occam's Razor would suggest strongly that it was your friend who fired those shots.
His memory CAN'T be counted on as absolute, and doesn't mean he's being deceptive, or that his intelligence level is sub-par.
Statements from other witnesses present, police or civilian, MAY be more reliable.
If it can be determined by witnesses that no one else fired (the fact of WHO fired is just as important here as HOW MANY ROUNDS WERE FIRED), analysis of all weapons on scene shows ONLY YOUR BUDDY'S GLOCK WAS RECENTLY FIRED, the dead man was struck by more than one intact bullet, your buddy's pistol can be forensically shown to have fired the single recovered case (showing he DID FIRE), and there are indications that the pistol when taken from the buddy was found two rounds short of full capacity, a conclusion is not hard to reach.
I'm not saying it's an absolute 100% slam dunk that he fired twice, but....
