Chasing down the egg-thrower, cornering him in a blind alley, pointing a gun at him... I'm thinking that at some point this kid ceased to be a threat to the shooter's existence. Pretty sure it was some time before the sixth round was capped off.
Just hypothesizing here, but it does seem like the driver was not a fine upstanding member of society, if you know what I mean. Where I work, we have a REAL problem with these drug dealer goons coming down from Columbus - drive by shootings, etc. I hope they catch who did it & he gets the proper punishment.
Still though, I would never have done something like those boys did when I was younger, (A) because my parents made a point to teach me early on not to trespass or vandalise other people's property and (B) because my parents would not have let me run around with other kids that did.
It still boils down to parents making sure their kids behave themselves. In the end, it was the kid's actions that prompted what happened to him and ultimately, caused the reaction that ended his life. Sad and tragic no matter how you look at it. However, I believe a 14 year old is old enough to know right from wrong - sounds like this kid was heading in the wrong direction and probably would have been a larger problem on society sometime in the future when he became an adult.
