I beg to disagree
They caused the death of a human.
They should be destroyed. Even if it was a "intruder", he should not/doesn't deserve to be executed like that, being been mauled to death by animals.
They will do it again.
“They will do it again” I don’t think they will ever have the opportunity. Everyone now knows not to rob that house!
That is such a brilliant statement that if I knew the address of the person who wrote it I’d post it at the exit to the local jail with their comments and wish them good luck.
Let’s hope they do it again in the same or similar circumstances. They are guard dogs. This is what they do. If someone does not want to meet them, don’t break in the house they are guarding. Easy and not hard to understand.
