Frank Palko thought the Fifth Amendment ban on double jeopardy applied to his case because he was tried for first degree murder. he was tried for second degree murder. he was first sentenced to life imprisonment. he was tried twice for the same crime.

he was tried twice for the same crime.

Explanation:

Double jeopardy clause occurs when a person is put on trial for an offense of which he has already been put on trial before. United States Constitution, states that no "person be subject for the same offense to be twice put in jeopardy of life or limb..."

This can only apply if the accused has already gotten a valid acquittal from a law court or conviction within the same jurisdiction. If this occurs, then the government or prosecutor cannot retry the accused/defendant.

Therefore, Frank Palko believed that double jeopardy would apply in his case because he was tried twice for the same crime.

assessment is the missing word
