Just an FYI for those appalled by the time involved...
The only defense case I have ever worked as an expert witness on involved a negligent discharge post pistol cleaning in which a subject injured his girlfriend. Nice to work a case where I could say the client was an idiot. The prosecution was looking for 10 years. My biggest run was what this guy did was something that happens to LEO’s and military folks often enough to not be a surprise when it does. Most of these are accidents often caused by negligence, and civil court is often the remedy. Gross negligence is a bit different and even so the penalties need to be in line with other stuff.
From a learning standpoint.....there are numerous lessons on this one. One I have taken away is that I am thankful that my lifelong decision to not leave a striker gun laying on a nightstand unsecured is a good one.
