The police officer violates the fifth amendment of the USA constitution.
No one may be tried for a capital offense or other infamous crime without a grand jury's presentment or indictment, with the exception of cases involving members of the armed forces or the militia who are serving in actual combat or other times of public danger; no one may be twice put in danger of losing their life or limb for the same offense; no one may be forced to testify against themselves in a criminal case; and no one may be deprived of their life, liberty, or property.
The Fifth Amendment stipulates that felonies can only be tried after a grand jury has indicted the defendant. Another clause, known as the Double Jeopardy Clause, guarantees that defendants will only ever face one trial in federal court for the same offense.
