Expulsion decrees punished all Moriscos collectively for alleged acts of a few.

Evidence

Once again, the idea of collective responsibility is brought forward. All the Moriscos must pay the penalty for what some are alleged to have done. … Curiously, the wording of the ban on the export of currency and valuables is repeated unchanged from the earlier edicts, but then the text closes, “But although it is forbidden to them by the laws of these realms, if any of them should wish to take out their property in money, silver and jewels they may do so, so long as they register it, and hand over half of it to my treasury [emphasis added] to the person appointed to receive such things, as the other Moriscos who left have done, but in this case they may not take goods with them.” This, then, allows those expelled to follow a similar procedure to that briefly in place on the Burgos-Canfranc route, although on less advantageous terms. The former Mudejars of Castile people who had never given any trouble to the Crown whatsoever, were given this reward: they only had half of their money confiscated, instead of all of it, and they lost all of their chattels! — L.
