Least competent criminals

Adam Grennan, 39, did not make it out of the Mt. Washington Bank in Dorchester, Mass., in December. So intent was he in not appearing nervous that he waited patiently in line, eyes straight ahead, until the time came to hand the teller his holdup note. He did not notice that a uniformed Boston police officer, working security, had slipped quietly behind him in line, and he arrested Grennan immediately as Grennan was quietly demanding large bills and "no funny money."
