Has nothing to do with disturbing the peace. The crowd was demanding the merchant give up his items to them. It had a good motive, but they went about it in a chaotic manner. The merchant had a lawful explanation on how he did it, but a neutral/evil reason for doing it.
Lawful/Chaotic is the manner in which you achieve something. Good/Neutral/Evil is your motives. So helping the merchant out, simply because you feel the mob is wrong would be Lawful Neutral. Getting paid to do the same would make it borderline Lawful Evil, but probably still Neutral. Threatening the crowd to take off lest you start breaking heads, changes the Lawful to Chaotic, but retains the motive. At least, that's my opinion.
