Why would it take weeks or months to know cause of death???
If it was in fact a training accident then the cause should be forthcoming — unless it wasn’t a training accident.
Why?
Because our government lies to us, constantly, and about almost every topic they mention. The lies usually revolve around ensuring the covering up of incompetence, or wrongdoing. It might be to insulate a defense contractor who built a crappy product. Maybe they didnt have some gear they should have had. Maybe a sequestration “show cut” like air traffic control or something caused the deaths and THAt needs to be hidden.
Or even something as simple as they just think it’s a bad week to discuss it politically.
But they simply will never tell us the truth.
