[DC] How are people able to shoot Superman with Kryptonite bullets?

It seems like a strikingly common occurrence for a guy who's known for being far faster than a speeding bullet.  Off the top of my head it happens in *Superman/Batman:  Public Enemies*, *Justice League:  Doom*, and multiple times in the series *Smallville*.

Well, one of *Smallville*'s regular criticisms was that it's possible to sneak up on the guy with super-hearing, so during the course of the show, Clark didn't have the best handle on his super-senses.

In *Doom*, he was already incapacitated by Metallo, so shooting him after that was easy.

As for the rest, they probably get hit with bullets all the time like it ain't no thang. Kryptonite bullets may come as a surprise.
