Well, I have some sympathy for the dog handler.
Yes, i am an animal lover and also feel that it was a tragic outcome for the dogs but i am also a student of human behaviour and human failings.
This handler had a love and devotion to his dogs as always is the case in these dog handler situations and just put yourself for a moment in the position of the policeman. A hot day, unusual in the UK, he, probably thinking of a dozen other problems on his way to a meeting, might or might not be late, gets out of that car and for one split second forgot to open the windows
In that moment there ensues a series of events that lead to the death of two dogs....a mistake...a tragic mistake....but how many of us can say that we have not made mistakes in our lives, some we may have got away with by the "Grace of God"
This guy was beside himself with grief and tried to commit suicide while his state of mind was unbalanced due to his mistake.
For the dogs, it is over.....but for him it is something that he will have to ive with for the rest of his life.
I for one, extend my sympathies.
