Eric Williams Correctional Officer Protection Act of 2015

Amends the federal criminal code to require the Director of the Bureau of Prisons to issue oleoresin capsicum spray to: (1) any Bureau officer or employee employed in a prison that is not a minimum or low security prison who may respond to an emergency situation in such prison; and (2) such additional prison officers and employees as the Director deems appropriate, subject to specified requirements.

Requires any such officer or employee to complete a training course before being issued such spray and annual training on the use of such spray.

Authorizes Bureau officers and employees issued such spray to use it to reduce acts of violence committed by prisoners and prison visitors against themselves, other prisoners and visitors, and Bureau officers and employees.

Directs the Comptroller General, not later than three years after the date on which the Director begins to issue oleoresin capsicum spray to Bureau officers and employees, to submit to Congress a report that includes: (1) an evaluation of the effectiveness of issuing such spray on reducing crime in such prisons and acts of violence committed by prisoners against themselves and others, (2) an evaluation of the advisability of issuing such spray, and (3) recommendations to improve the safety of Bureau officers and employees in prisons.
