How is a 67-year-old a threat to 1 , let alone 2, youts? How would talking to the guy for a minute or two have hurt? What, he was going to whip both of them at the same time? Please, these guys escalated because they WANTED to hurt someone different from them. So they attacked an old guy incapable of defending himself, and gave him serious injuries - throw away the key, society will benefit immensely.
I agree. Could they not tell he was just confused and had the wrong car? They are just thugs. Lock them up forever. Animals belong in a cage.
