It's another instance of 'force protection' taken to extreme levels, soldiers see a silhoulette or
flashlight directed at them, & shoot said silhoulette.

On Sunday, IDF troops killed a 64-year-old man in Jenin, it was released for publication Monday.
Palestinian sources said on Monday that Sabri Khalil worked as a night watchman at a local school. After he shined his flashlight on a passing car, soldiers patrolling the city shot him in the chest, killing him.
The IDF confirmed that soldiers shot a Palestinian standing on a rooftop, saying he had apparently been holding a weapon at the time. An army spokesman said that in retrospect, it appears that the man was holding a flashlight.
The army is investigating the incident.
