Final answer:
Mason will most likely be prosecuted for state-level crimes by a prosecutor representing the State of Oregon, which aligns with option D. The case involves burglary and theft, not drug trafficking or federal drug policy enforcement.
Step-by-step explanation:
Considering the given scenarios, Mason is facing prosecution for a sequence of burglaries at UO student apartments where items such as laptops and cash were stolen. Given the specifics of the case, it is D. Mason will be prosecuted for state-level crimes by a prosecutor representing the State of Oregon. The Drug Enforcement Administration (DEA) typically investigates drug trafficking and distribution rather than burglaries, making option A unlikely. Deportation actions, as mentioned in option B, are not automatic based on citizenship status but rather involve a complex legal process if someone is found to be unlawfully present, and Mason's case pertains to burglary and theft, not immigration violations. Option C is implausible as the federal court would not typically handle a series of local burglaries just because they are part of a broader issue such as the war on drugs, unless there's evidence of larger federal crimes. Federal laws like the Controlled Substances Act (CSA) regard marijuana as illegal, despite states' stance on legalization for medicinal or recreational use. However, the federal government's enforcement is limited and largely relies on states' cooperation. The shift in public opinion toward the decriminalization and legalization of marijuana has influenced policies, including shifts in Justice Department approaches, yet this case concerns theft, not drug policy.
