I would tend to agree. When they interviewed one of the FD guys, he said if he wasn't on duty he would have rescued the guy. However, because they aren't certified, it opens the department up to lawsuits if something goes wrong. That's great. So now we have public officials that are doing more harm than good because of the lack of resources to train them and the fear of liability if they don't successfully save someone's life. I'm not sure which is more frustrating.
It's the same reason why doctors aren't supposed to stop to help people at the side of the road - they aren't protected by good samaritan laws. If something goes wrong, they could be liable for it, even if the person would have died without intervention.
That being said, I think most doctors would do it anyway.
