Let me shut down your argument right away about the kid.
When Omar and crew crashed the door...the brought Stink and the pit workers into the apt.....dj clue...the young kid were the ones inside (who knew where the drugs were).....they caught another guy coming down the stairs....but dj clue and the young kid were the ones inside.....Omar and crew staked it out and knew what was what.
He didn't aim at the kid because of the reason you mentioned, but because he and clue-minatti were the ones who were inside the spot when they crashed in....Poot,Bodie, Stink and whoever else they forced inside were outside when the drop was being made.
You created a scenario to fit your viewpoint, but the way the scene plays out..more than likely it's how I described it.
I think the mistake some people make is that they watch the show with commentary on, so their views and interpretations aren't their own..but how the writers/directors see it..(or they watch with closed captions)
For example....dj clue was a minor character....I've watched the entire series about 10 times..and NEVER noted or heard his name. How did you know his name was Sterling? Closed captioning? commentary? Did another character later mention him getting shot?
Well it looks like you will need to watch 11 times then. Clearly you're not as observant as you think. I've never watched this or any show with commentary on. That shyt is annoying. Have I watched special features on DVDs? Absolutely.
However that's not how I know Sterlings name. He was a minor character...but he had a name. D'Angelo had mentioned it before when he found out STERLING and CASS were stealing. Cass was the girl whose eggs D'Angelo broke when he caught her coming from the store. You remember. String told D to hold that paper and whatever workers weren't pressing him to get paid were the ones who were stealing.
Wallace and D were having a talk. Wallace asked "why you bust Sterling down to lookout? He got shot in the leg behind this shyt". D explained he demoted him rather than tell String because Sterling and Cass woulda got a bat beatdown...at a minimum.
To quote "Cool Lester Smooth", 'It's all in the details'. So go head and give the series another watch. That's what makes this the greatest show on TV of all time. You can always find something new when you re-watch.
And just cuz you missed something, don't mean it wasn't there. I see what you tried to do there, youngin
