Two things you need to know.
First of all, we are talking about really low level guard NPCs with [REDACTED] EQ that shouldn't be a real threat to any of the high lvl PCs in the game.
Also, this place sucks for traps. Opening rifts to other places in the same general area can be much more deadly with slight preparation. Plus back then it would result in really bad things(read: banishments). And
here is a small example.
Generally though, the script is needed. Perhaps it should be removed from some NPC in that room, because I see that CoN members nowadays "abuse" it and this makes me a sad panda. But I consider this script necessary for at least 2 other NPCs in this area.
PS: This script actually becomes a pain in the [REDACTED] for any CoN member who uses certain abilities of the law NPCs. I know if I was an enemy of the CoN, I'd try to use it once in a while to cause big trouble to CoN members.
