Forgotten Weapons has a great video about this whole issue. I found it odd that there's been no actual evidence of the guns misfiring, dropped or otherwise, and there's been no mechanical explanation given as to why they're "misfiring". It's all based cases like this where we're just taking peoples' word for it and it's to the point that the Air Force is burning money on a review.
This dude is gonna be made an example of if he's proven guilty...
