Boeing execs are basically high ranking CIA for all intents and purposes, which makes them untouchable. On top of that, Boeing has been hollowing itself out by subcontracting production off to spinoff companies which then subcontract that out work out to someone else and records never seem to exist when something goes oops. Minimum liability and maximum profit.

In Amerikkka, the only Boeing people who get the death penalty are the whistleblowers.
