If you watch TV and films, you’ll notice that there are lots of shows about robbing banks but not many about stopping people from doing it. There is a very good reason for that. It’s much easier to write an exciting piece of entertainment about getting the money. The writer can throw in all kinds of stereotypes. The angry mob guy who’s going to go rogue, the weak one who doesn’t want to be there, the old experienced criminal who’s seen and done it all and finally, the idealistic young one (who may or may not be an undercover cop). It also gives the writer the chance to come up with some tense scenes in the bank or a clever ruse, so that bank staff don’t know they’ve been robbed until much later.
It’s much easier to do that than to have a charismatic person going around to lots of different banks, checking that their security is up to date. Where is the fun and excitement in that? The only time that would work in a story is if the security officer was planning a robbery themselves.
The other thing that writers forget is what the robbers are supposed to do with the money they’ve stolen afterwards. It’s not like they can waltz back into the Branch and open an account. (although some have tried). Financial institutions use AML IDENTITY CHECK tech. Like that provided by https://www.w2globaldata.com/regulatory-compliance-solutions-and-software/aml-id-checks/ to make sure all is as it should be.
