Looks like ALF is up to it again, I hope that if and when the vandals are arrested that they are prosecuted as domestic terrorists, for that is what they really are.
We need to send a message that these type of actions will not be tolerated in our society. This incident was mild, but if left unchecked, the participants of this action will only escalate the severity of their future actions. As was seen in the arson attack that destroyed half of a new subdivision being built, by other teams belonging under the umbrella of this fanatical group, the incidents may start small, but end up in a society destroying maelstrom.
The reasons given for these acts of terrorism might be a noble (misguided and misinformed, IMO) impulse, but the results of misguded idealistic zealotry are not only counterproductive to their goal; they are destructive of the society that engendered those impulses.
