Um, no. They were known for the speed at which they were in and out of the bank and away before police could arrive. They were spotted and reported going into the bank and by luck police got there far quicker than in the past.No they were fools. They robbed a bank very slowly and loudly.
Robbing banks and GETTING AWAY WITH IT is actually quite difficult. They successfully did this many times.Robbing banks isn't that difficult, but it is much easier without body armor, pills and machine guns.
Their quick entry with gunshots into the ceiling was very effective at gaining quick compliance from everyone in the bank. A robber with a revolver or just a note to the teller can't get that sort of quick compliance, though they will frequently get a dye bomb.
How exactly would they have made a quick getaway in that situation? A space rocket? Seriously, I wanna know. The cops have cars too and helicopters seem to have no problem following cars either. Their plan relied on getting away before police arrived and melting into traffic. Staying and shooting it out was no more stupid that trying to drive away because no matter what they were screwed at that point.When discovered by police instead of surrendering or making a quick get away they chose to stand and fight against a police department.
