Quite often it is because the individual has outstanding warrants, is on probation, or is on parole, in which case even minor infractions could mean going back to prison.
This would be my guess... It was a black female officer that was trying to open the drivers door. She unassed the area right quick when the kid opened up on her...
After that... sounds like each cop dropped two full mags each at the vehicle and in to the kid. Guessing only a few bullets actually hit him. That was enough though.
Jail for outstanding warrants or for probation/parole violations? In Governor Fatass Pritzker’s No Cash Bail paradise? Ha! Ha! Ha!
