Given his physique, it shouldn't take a Harvard degree to spot this guy...

From this morning's Boston Globe, page B2, "Harvard puts out warning after robbery":

Harvard University officials are warning students, faculty, and staff to be vigilant and take precautions, after an armed robbery early Thursday in historic Harvard Yard. A male unaffiliated with the university was robbed at gunpoint by an unknown male as he walked through the yard near Thayer Hall, a freshman dormitory, about 2:45 a.m. Thursday, an advisory posted on the university police department's website said. The robber was described as a Hispanic man in his 20s, 55 feet 9 inches tall with a thin build, facial hair, and dark clothing, including a black baseball hat. Police asked anyone with information to call Harvard police....

So, if you see a 55-foot-tall man striding across Harvard Yard, be suspicious.
