Fair enough, I'm no medieval scholar, I am/was merely commenting with the interpretation that Chris Wickham (who is) had in his book "The Inheritance Of Rome", where he begins his chapter "The caging of the peasantry" with a brief discussion of this event (and a translation that looks a bit more like the one done from the Latin by the other commenter).

He does point out that the meaning of "incaute" is ambiguous here, but the salient point still stands: that military service was forbidden from the common people and that an organized common people was not allowed, and dangerous. It is speculative but he comments that these peasants may have felt they were following in the footsteps of their grandfathers who would have rightfully assembled for defense in time of need, and in fact that had formerly been the prerogative of free peasants.

So the point still pretty much stands regardless, the language speaks of free peasants self-organizing as a threat and an easily defeated one.
