The public safety exception in the above cited case amounted to exigent circumstances. Had the question not been answered, the gun might have been found by someone with nefarious intent or a child who might irresponsibly use it.
Law enforcement has had all the time in the world to comply with Miranda, as silly as it is. As much as I disagree with the Miranda ruling (and, consequently, the need for a public safety exception), as a matter of practicality, I am convinced that LE will be found not to have a public safety exception in this case, therefore jeopardizing the case against this vile bomber.
Dumb.
Guys, just fill the square. Odds are you won't be telling him something that he has not heard on TV a thousand times before. Not mirandizing him will likely have zero effect on whether he talks or not.
Dumb.
