A further factor making bank robbery unattractive for criminals in the United States is the severity with which it is prosecuted. United States Federal Sentencing Guidelines for bank robbery gives long prison terms, which are usually further enhanced by the use or carrying of loaded firearms, prior criminal convictions, and the absence of parole from the federal prison system. As with any type of robbery, the fact that bank robbery is also inherently a violent crime typically causes corrections administrators to place imprisoned bank robbers in harsher high-security institutions.
