Threatening the President of the United States is a class E felony under United States Code Title 18, Section 871. The offense is punishable by up to 5 years in prison, a $250,000 maximum fine, a $100 special assessment, and 3 years of supervised release. Internet restrictions such as a prohibition on access to email have been imposed on offenders who made their threats by computer. The U.S. Sentencing Guidelines set a base offense level of 12 for sending threatening communication, but when a threat to the President is involved, a 6-level "official victim" enhancement applies. Moreover, "an upward departure may be warranted due to the potential disruption of the governmental function." Further enhancements can apply if the offender evidenced an intent to carry out the threat (6-level enhancement); made more than two threats (2-level enhancement); caused substantial disruption of public, governmental, or business functions or services (4-level enhancement); or created a substantial risk of inciting others to harm federal officials (2-level enhancement). Since each 6-level increase approximately doubles the Guidelines sentencing range, it is not particularly rare for an offender who threatens the President to receive a sentence at or near the maximum, especially if he has a criminal history and/or does not qualify for a reduction for acceptance of responsibility. There is a 4-level decrease available for a threat involving a "single instance evidencing little or no deliberation", which would usually apply to spur-of-the-moment verbal threats. The maximum penalty for threatening a United States judge or a Federal law enforcement officer is 10 years imprisonment — double the maximum penalty for threatening the President.
