I think you're right. If the cop overreacts, as they tend to do, I bet the pet owner beats them in court. Temporary insanity would be the defense, I guess, and with a good lawyer talking to a jury, the party might walk out of the court, a free man or a free woman.
Nope, the other cops would execute the homeowner.
As for the main story, it shows what a worthless piece of ___ the DA is for not charging the trigger happy Irish with child endangerment and injury to a child.
