Which of the following crimes would be tried in a federal court?
a) a burglary that takes place in a private home
b) the murder of an on-duty police officer
c) attempted murder by mail bomb
d) drug possession in a public park

C) Attempted murder by mail bomb

Explanation:

Federal crimes are committed against the nation's laws and institutions, and are out of the jurisdiction of cities and states. In the US, the postal system is federally administrated and a mail bomb would be a federal crime since it's using a federal institution to attempt to commit a crime. Public parks, private homes and police departments are under state or city jurisdiction, so they wouldn't reach the federal level unless appealed several times.
