Begging to be caught
If the accident hadn't happened and an investigation had been launched they would've been caught in no time. The fact that they actually thought it was a good idea to commit other crimes to "psychologically test" themselves shows what imbeciles they were. If you are going to commit a big crime like that and try to get away with it, you don't want to be noticed by the police at all for doing stupid crap like robbing a Safeway or your boyfriend's store. Plus they actually record a tape talking about their plans that could be used as evidence against them and none of them wear gloves when executing the crime, thereby leaving fingerprints all over the places that police WOULD investigate later. Then Jane Curtin's character does a strip tease and even calls the guards to come up on stage during the robbery after her attempt to cut the lights(touches the switch without gloves) fails. If you don't think the police would put it together that there's a woman suddenly stripping naked in a shopping mall at the exact time it is being robbed and figure out it was a diversion then you are deluded. Heck, if they decided that someone used a shop vac in the robbery-not an impossible conclusion-they'd very likely take note if a shop vac was reported missing by her boyfriend's boss so soon before the robbery and put that together with the strip tease and they would go to jail. Further, standing in front of the ball and discussing the planned crime was idiotic. Only one of them should've been there at a time and they should've discussed it only when they were some place where they couldn't be overheard. Dating a cop when you are planning and executing the heist isn't very smart, either-nor is spending money you obviously shouldn't have 25,000 or 10,000 at a time so soon after the robbery. That said it was a somewhat enjoyable movie and I nostalgia-ed hard watching it.
