James Guelff Body Armor Act of 2001 - Directs the United States Sentencing Commission to review and amend the Federal sentencing guidelines and policy statements to provide an appropriate enhancement for any crime of violence or drug trafficking crime in which the defendant used body armor. Expresses the sense of Congress that any such sentencing enhancement be at least two levels.

Amends the Brady Handgun Violence Prevention Act to prohibit the purchase, ownership, or possession of body armor by violent felons. Makes it an affirmative defense that: (1) the defendant obtained prior written certification from his or her employer that the defendant's purchase, use, or possession of body armor was necessary for the safe performance of lawful business activity; and (2) the use and possession by the defendant were limited to the course of such performance. Sets penalties for violations.

Authorizes the head of a Federal agency to donate body armor that is surplus property and in serviceable condition, and that meets or exceeds National Institute of Justice Standard 0101.03, directly to any State or local law enforcement agency. Allows specified officials in the Treasury and Justice Departments to act as the head of a Federal agency.

Specifies that the United States shall not be liable for any harm occurring in connection with the use or misuse of any body armor donated under this Act.
