I don't agree with hanging a crew either, unless there was a wilful act of negligence with a "hey watch this" (which almost never happens). Most likely this crew had every intention of flying safely from OAK to BUR that day.
Every airline - including the one every criticizer here works for - has had an incident/accident in the past including excursions like these. The "this would never happen to me" crowd this early in the game is bravado at best.
