Manslaughter != murder, thats a difference between 3 years and 15-to-life in prison (not in Norway though).
Also, don't fall under the spell of some absolute fairness of our current societies, of course ultra rich are treated differently than regular Joe (or ie former presidents, prime ministers, olympic gold medalists etc), at least until mass media gets in. And Boeing is a strategic military provider not only to US, more a typical 'too-big-to-fail' category.
But if it would be 3 years per manslaughter, it would add up to life in prison, since we are talking about hundreds of dead people. (but no idea if this is how it would work, I know it is like this with other cases).
And surely we know that society is not fair. That does not mean, we have to accept that.
In Germany, there was a murder case of someone driving a car with over 100km/h through a city and killing a pedestrian. Not manslaughter, murder. Who conspires to maximise profit when putting a new plane design in the air by circumventing safety rules, lying to regulators and pilots, shutting up whistle blowers and in general ignoring safety during construction, aims at killing people. That's premeditated. That's murder.
Probably not. _3u10 is right, this is only a fraud case. And Boeing is also providing military hardware, so under full government protection. Trump would pardon them directly, Biden just not foster a DOJ the investigation, while the three letter agencies will do their usual work to keep the civilians at bay. At least that's what I would suspect.
This is what happened in Canada when SNC Lavalin paid millions in bribes to Gadaffi in Libya. They fired the attorney general who wanted to prosecute them.
And let’s not be under illusion that if my actions accidentally resulted in deaths of hundreds of people I would see any fresh air ever again
