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).
