Are the Police service unable to learn from their mistakes?

They've done it again - another 2 dogs (one only a puppy)

That's awful! D:

Just horrible. Those poor dogs :-(

It just beggars belief, that Police Officers who have working dogs in their care can act in such a cruel way, are they thick or what?, if a member of the public were to do this they would throw the book at us, the Officers in question, need to be taken to task pronto!
