Then they ran up and shot him right in front of his mom
This most likely refers to shootings such as that of Darius Simmons, who was killed in front of his mother by elderly neighbor John Henry Spooner on June 4, 2012. Note how this sets up the imagery of black-on-black inner-city violence that was alluded to a little earlier in the verse and will now take center stage for the next few lines
However, the use of “him” in this line cannot be overlooked, as it continues the previous few bars in which Kanye is referring to himself in third person pronoun. “Shooting” in this sense could be subtle but familiar wordplay concerning the paparazzi taking pictures of Kanye when he was with his mom & dragging him through the mud in front of her, putting more pressure on her, and leading to her later-fatal cosmetic surgeries
He’s also still reffering to the police as in his previous lines. People or the police don’t see the story of the man they’re robbing or “arresting”. This person (Sean or Kanye, or 3rd person) has come from the bottom and now has enough to support his mother and buy her a dream home. But the police just run up and murder him right in front of her. All because of his money, they either wanted to rob him or the police are unjustly killing him because they ASSUME he’s a drug dealer or has broken some law to acquire all this wealth.
