Have you ever seen a bank vault? Its not just a door with a masterlock on it, its very complicated to open and usually requires at least a manager, usually 2.
idk if this has been said, but they only lasted so long because the police weren't issued assault rifles back in the 90s. So their bullet proof vests stood up against the cops pistol rounds. Had the police been issued assault rifles, those two guys would not have stood a chance or caused as much damage as they did (rifle rounds penetrate body armor). You see towards the end that one guy had a gun jam and pulled out his pistol. People say he either shot himself as suicide, or on accident while trying to reload with one hand. The other guy was finally taken down because swat showed up with guns that could penetrate the armor. Mine while, a couple of police officers were at a local gun store trying to get guns that could penetrate the armor.
problem with that is the size of the emp blast. and most banks during hours of operation have the vault open, albeit the larger ones have gaurds
so if he got a big enough emp blast it would take out the cop cars, their radios, and all other forms of communication. which means no coordination and extremely slow response time. walk in force everyone down take untracables from vault and haul ass out ditching equipment weapons and head to a private chartered/owned plain and go to a non extradition country
*my sspelling and grammar are atrocious, deal with it like i have to at work with all the messed up application forms*
Watch the banks for several days or weeks and learn who works when, manager, time it opens, etc. When the bank first opens walk in normally but right before you enter the door shut off the power which eliminates the cameras. Continue inside and make sure all the employees are not behind the desk or bullet proof glass because they will be able to press the secret red button and make them all sit in a spot not visible from the outside but not reaching any items, phones, etc. One keeps watch and another begins cutting bars since today's vaults are timed and only open during a certain part of the day so you'll haft to work threw that. Once done cutting and collecting take all the people and put them in a closed room and take any communications they may have. Walk out normally get in the car and drive away like nothing happened. Now all this needs to be done within 5-7 minutes because people are bound to come in and police may come and check in every so often another thing you will haft to watch for.
