Capt...you harbor a lot of anger over this and your boss. Great White the band hire a manager who inturn hires soundman, pyro.ect. The band went on like a thousand times before and a building that was not up to code went up. If my daughter died there I would be angry. Then I would allow the professionals who invesigate these for a living do there job. The band was found not at fault and thats good for me.
According to you anyone that kills someone by "accident" should never come out in the light of day myself. Did you ever adjust your radio when driving? Your A/C? Maybe a family member called you on your cell in the car? If you say no to these common mistakes we all make, incuding myself, then you are not being truthful. And I hope if you ever make a mistake the people who are judging you let you out in the world. PS: I am sure like Great White, the guy that killed your boss lives with what he did everyday....and that is not fun!
