Other mistake: The plea deal with Danny (5 to 7 years in prison) seems inconsistent with Georgia's sentencing guidelines, recidivist law, and the State's reputation as being tough on repeat offenders. Danny was on parole, which means he was convicted of a felony. His new charges - including assaulting a police officer (an "aggravating circumstance") and possession with intent to deliver - could be enough to impose MAXIMUM sentences or mandatory minimums (10 years?) under sentencing enhancements.
Plot hole: It doesn't make sense for the prosecuting attorney to agree to accept a guilty plea from Danny for assaulting an officer, possession with intent to distribute, and resisting arrest with no accompanying guilty plea for at least a lesser-included offense of murder (such as voluntary manslaughter). A violent gang member committing an initiation murder while out on parole would be dealt with much more harshly, especially when the murder victim was a high-school-aged teenager and random victim.
