It seems to me neighborhood watches and security patrols would be a better alternative than vigilante justice. I used to volunteer for the angels night patrols in Detroit. I don't know how you expected a 60 year old to beat down two 20 year olds. Apparently he couldn't since they ended up beating him. Simply put police have to do their job. If the one comment was accurate, police were there right away. If he would've called police first, they would've been there and caught the criminals. Instead he approached the criminals, got jumped, and called police after they were gone.
