Well, if you want folks to comment and offer up an intelligent outsider opinion as to the situation that occurred then you need to provide as much factual, actual information as possible.
Since none of us were there with you we can only comment on what you type as fact and we cannot speculate as to what you leave out.
I'm sure that the entire event that transpired has you quite upset but, the graphic imagery of the event that you're attempting to create should be secondary to making certain that your story is inclusive of all the relevant facts.
I would say that if your scenario (as you've related it) is what happened and that if the fact that the LEO firearm was pointed at your wife with the LEO finger on the trigger then you should absolutely get that issue resolved in any way possible.
Would this all be on the LEO cruiser Vid Cam?
If so then I would have your attorney request and review that and then go from there.
