He gave them a warning and they ignored it. One ran toward him then ran at an angle and he shot him.
Who was going to be next? Maybe someone would have been home at their next victim's house. Two illegals start breaking into houses and somehow people choose to defend THEM. The 911 operator is not a law enforcement officer so their SUGGESTION to stay inside is just that, a suggestion. How long should he have let these two continue burglarizing his neighborhood?
Here's a novel idea, don't commit crimes and you won't get shot.
