Jake takes the marijuana, but Alonzo tells him later on that it was laced with PCP. This event provides a perfect set up for ensuing scenes. From this action, for example, Alonzo would later threaten to kill Jake for refusing to participate in one of his illicit crimes boasting that the blood tests from Jake’s corpse would reveal the presence of PCP, and thus discredit Jake.
In the next instance too, Jake spots and subdues attackers who are sexually assaulting a certain high school girl called Letty while Alonzo simply watches. Alonzo orders Letty to leave instead of recording a statement at the police station, telling a shocked Jake that street justice had been served since the two perpetrators had lost their drugs and money, and would inevitably be dealt with by Letty’s vengeful cousins. Alonzo does well to prime Jake and the audience for what is yet to come (the ‘bigger’ crimes) and attempts to tune Jake’s mind so that in the consequent ‘errands’, Jake would be okay with the corrupt dealings. As we see in the later stages of the film, taking crime money from criminals instead of handing it in as evidence was street justice in Alonzo’s perspective, and it is this point of view that he tries to instill in Jake in the incident with Letty.
In the third circumstance, Alonzo meets a group of elite police officers, otherwise known as ‘The Three Wise Men’. They tell Alonzo to leave the town since it had come to their knowledge that Alonzo owed money to the Russian Mafia which put his life at risk.
