This 80 years old man dun have the survival instinct and should learn to work smart. This type of security patrols should rightfully be done with a partner. Even police do it in pairs. Approaching a stranger with the intent to chase him away, he should at least size up the stranger whether he can handle him physically alone. If he has no confidence, he could have close one eyes and pretended that he did not see him sleeping on the bench or call the authority or help to chase that bugger away. Instead he eyes close close and bulldoze up to that stranger and ended up kena whacked.
