The story is confusing as there are two dog shootings being reported on.
Apparently, the pictured man shot a pit bull in his own back yard, made claims that the dog was loose several times... etc.
At any rate, he shot the dog... and the other shootings reported raised the ire of the animal rights folks.
Something to think about, should you ever have to defend yourself from a dog... animal cruelty charges. In some locales, the SPCA, "Animal Control" and similar have more pull than LEO.
