Certainly the violence link, as it's commonly called, between people who commit acts of animal cruelty and people who commit acts of human cruelty is well established and has been well established in academic literature for quite some time. It is important to recognize that from a human perspective so that if someone does commit an act of animal cruelty, obviously against an animal, then getting them into the system and getting them on the radar screen is important to de-escalate them from committing an act against a human. We have some very popular cases right now that illustrate that point. Had Luka Magnotta been charged with animal cruelty for what he was doing to those kittens early on, perhaps he would not have had a chance to escalate to humans.
With regard to any animal cruelty, that is the case. I would argue that it's the same case for an enforcement animal. But it's possibly even more the case that if you're willing to attack a service animal, you may have a propensity to attack a human.
