So what's the "public safety exception" about then? We're starting from the position that, absent a public safety concern, the defendant's right to know his rights is greater than the law enforcement interest in not encouraging the defendant to exercise them, and if the cops don't read the Miranda rights then the statements aren't admissible. Now throw in a public safety issue -- the cops have to interrogate this guy…
The public safety exception strikes me as equivalent to the enemy combatant exception - a way to just skirt civil liberties when it seems relevant.

That's exactly what it is, with good reason. When this is used, we are saying that the rights of others trump the rights of this suspect. When we're talking about the possibility of active bombs hidden within a civilian population, I would think it's a no-brainer that the rights of the people to not be blown up trumps the suspect's rights.Also, as @anigbrowl says, this isn't going to be a case where the majority of evidence comes from the suspect's Miranda-less statements.
Edit: I will admit that this could hurt the suspect's eventual defense. Even if the statements aren't necessary to the prosecution's case, making them admissible in court could limit explanations put forth by the defendant.
