Now, my second response:
Thank God they worked to find the killer of this innocent kitty (all kitties can’t actually form “intent” no matter what they tell you at night). It is great they used DNA to bring this scumbag to ground.
In the old days, the police would have left this as “who cares?” But today it is clear (there are solid links) that killing of animals who can’t protect themselves is a pathological trait. It almost inevitably leads to the same treatment of humans.
