Least competent criminals

Too puny for a life of crime: Keith Bellanger, 20, failed in his attempted burglary in Duluth, Minn., in September when homeowner Wayne Boniface, age 69, walked in and beat him up so thoroughly that Bellanger had all his clothes ripped off trying to get away. And in Bay Shore, N.Y., in September, a 32- year-old man wielding a tire iron, who was attempting to mug Bruce Ferraro, 74, on the street, was forced to abandon the job and run for it when Ferraro, after a struggle, took the iron away from him. (The mugger was captured by police nearby when his car stalled.) ¦
