This bill — the Protect and Serve Act of 2018 — would make attacking a law enforcement officer a federal crime when the defendant, victim, or weapon used were involved in any interstate or international travel or commerce during the course of or prior to the attack. Causing or attempting to cause serious bodily harm to an officer under such circumstances would carry a prison term of up to 10 years plus a fine, while killing or kidnapping an officer would carry any term of years or life imprisonment.
