. >> reporter: leyland gregory knows all about stupid crooks. subject. he said the proliferation of security cameras and sites like youtube show that the average crook is no criminal master mind. gregory says many thieves seem to violate every rule of staging a successful crime. for example, a break-in should always be well planned. movies like "ocean's 11," criminals spend a lot of time hatching the scheme to get away with the loot. >> $150 million. >> reporter: but these crooks apparently can't be bothered. they simply smash their car through the front entrance of this hip hop clothing store in florida. they then snatch up as many clothes as they can, but on their way out, one of the cools gets pinned between the car and the door. ouch. yep. you better make sure you have good health insurance before you sign up to be a thief. watch this attempted break-in at a home in florida. the two burglars spend 15 minutes trying to open the side door. one of them apparently had enough. he gets into a football stance, then charges at the door at full speed
