Sentences for anybody given such powers when they do get caught breaking the Law and are actually prosecuted and found guity, should be at least double the sentences that people who had no such powers and inside influence in the Law Enforcement process get.

If they have a priviledged position within the legal system with powers which others do not have (including, directly or indirectly the power to make it less likely that they are made accountable for their own crimes), the punishment for breaking the Law if and when they do get caught, prosecuted and found guilty (a big IF) should reflect their superior familiarity with Criminal Law, their lower probability of getting caugh, prosecuted and found guilty because they're inside the very system that does it, and the fact that they abused the authority they were entrusted with.
