You will always get tagged packets for events on reassembled streams and
for any rule that has the tag keyword. You can associate these events if
you are using barnyard by the event ID, SIP, DIP, and ports IIRC. If you
are using BASE this is pretty easy to do.

Check out this post for a little more information.

removing the logging of the tagged packets would make analysis
impossible in many cases.
