My question involves juvenile law in the State of: Arizona
Jack sold someone supposedly name John a fairly large amount of cannabis. John said "I heard you got busted by the cops?" and Jack asked who told him multiple times and John simply laughed nervously. Jack asked John how old he was and he said 16 but John was extremely tall and looked like he was in his 20s. Jack said "dang you look like you're 20 man!" John again laughed nervously as if he didn't hear what Jack said. Couple of weeks later Jack finds out through sources that police think Jack's friend is dealing (John has previously stated he knows this friend, but Jack's friend does not know him) and that same night Jack sees two cops parked by his house waiting for Jack to come home, but Jack drove by them and went around and by that time they were gone. Also later that night John was asking Jack's friends where he was and if he got pulled over and if he could get more cannabis.
If Jack really did sell cannabis to an undercover police officer can a warrant be made for his arrest/search of home? Also, it could be a possibility that John could just be an informant, and if that's the case do the police still have enough reason to issue a warrant? The police in this town are known to harass the teenagers here as well, such as having multiple police cars shining lights at their windows and parking in front of their houses.
