I don’t know enough about the law in the USA to give an answer to your first point (whether the attempted murder allegations should factor into sentencing). However, to your second point: no, 7 years is not enough for attempted murder. Failing to commit a crime (because your hitmen were actually the police) is as morally reprehensible as succeeding. You performed the actions, formed intent, it’s just the victim got lucky. Your sentence shouldn’t be reduced because of their luck.
