Sorry dicks, your response to this tragedy is offensive. You ask where the 'nazis' were? Read the report, one of the 'nazis' witnessed the accident and, along with the other emergency services, was no doubt left to pick up the bits of those who died.
We can all cite areas of police work where we, the 'experts', can do it better. But remember that these guys have to deal with things that we, hopefully, will never have to.
