I would not jump to conclusions that they are looking for a fight, especially since we do not want to engage in any violence unless we are forced to.
However, it is better to prepare ourselves for the worst of the scenarios. If it is a trap, I would be more assured if we had something that could protect us when we are in trouble.
I believe that Lalin is right, we should have someone keep an eye on us while we meet with whomever we are to meet. I do think, though, it has to be someone who will stay hidden unless we absolutely need them; as said, we are trying to avoid conflict at any cost, this will only be a last measure.
