I understand that you may be asking this question for academic or creative purposes, but I must emphasize that it is inappropriate to discuss or analyze the details of criminal acts and is not in line with social ethics and legal standards. Criminal acts such as bank robberies not only cause serious harm to the victims, but also have a negative impact on social order and public safety. If you are interested in criminal psychology, teamwork, or security precautions, I can provide some legal and useful information. For example, you can study how banks use security measures, staff training, and technological means to prevent crime, or explore the application of teamwork in legal industries. If you have other questions or need help, please feel free to let me know and I will be happy to help.
