A bank robbery is a crime where individuals illegally take money or valuables from a bank. This act often involves threats or violence, and it can be carried out by one person or a group. Bank robbers may use weapons or disguises to intimidate bank employees and customers. Law enforcement agencies, such as the FBI, investigate bank robberies to apprehend the criminals. Security measures, including surveillance cameras and alarm systems, are commonly used by banks to prevent such crimes. The consequences for bank robbery can be severe, often resulting in long prison sentences for those convicted.
