While I have my own issues with the Unicorns and Mr. Zora, I do believe that this was done entirely in the best interest of the neutrals. While it was certainly not the wisest thing to do, it was really just Omni-Tek picking up the slack that the ICC should have had covered. Their guards were, at best, a nuiscance to troublemakers. The OTAF forces are only there to protect the Unicorn forces, who we all knew would come under fire from the Clanners. What their orders were, I cannot say, but what were the Clan guards' orders in Tir? At the very worst, it is the same kind of justice which the Clans so often use.
