After his deal with the previous arms dealer, Zac had some time before he had to return home.
He remembered the three people who had interrogated him earlier in the white van and couldn't help but start his revenge plan.
He knew their real identities. But he didn't have their addresses. How would he get to them?
For Zac, there were two ways. Access the men's smartphones, or go to the police and get access to the police system. Surely, there would be something that would lead him to the homes of these three through one of these two methods.
Going to the police was not a good option. Zac still couldn't hack into electronic systems far away from him. It would also be dangerous to do something like that against the police. On the other hand, he didn't know any cops who could help him.
If he tried to find a policeman for this job, he could easily get into trouble by running into an honest policeman or a policeman already committed to The Vipers.
