--So if a bank rober is stopped before he walks out of the bank with money - isn't not bank robery and the whole thing is forgotten? --

Interestingly, this is exactly the case for shoplifting.

Store detectives usually wait until someone actually goes past the checkout with a stolen item until arresting them, because that's when the crime has actually taken place.
