Are there hospitals that haven't fixed their computers yet? Obviously CS messed up, but aside from paying for damages and making process changes, I'm not sure what else they can do at this time. Warning people to not repeat their mistakes doesn't seem like a bad use of time.
CS deserves the blame here but putting CS into a critical system like 911 IMHO is a huge mistake (but whoever done this likely knew they will dodge the blame so why they should care).
