Am I missing something here?

Yes, the fact that if you're doing TCP resets, you really want to send a tcp reset to the destination of the attack, not the source. This may or may not be the same interface that the attack came in on, particularly if your snort sensor is running on a routing box.

And taps really aren't that special of a case, or at least shouldn't be. Of course, I also suspect most snort users aren't careful enough to be running snort chroot/setuid either (sigh).
