so I called the police.
Boy, do I feel silly now.

Harvard professor Henry Louis Gates Jr., one of the nation's pre-eminent African-American scholars, was arrested Thursday afternoon at his home by Cambridge police investigating a possible break-in. The incident raised concerns among some Harvard faculty that Gates was a victim of racial profiling.
Police arrived at Gates’s Ware Street home near Harvard Square at 12:44 p.m. to question him. Gates, director of the W.E.B. Du Bois Institute for African and African American Research at Harvard, had trouble unlocking his door after it became jammed.
He was booked for disorderly conduct after “exhibiting loud and tumultuous behavior,†according to a police report. Gates accused the investigating officer of being a racist and told him he had "no idea who he was messing with,'' the report said.
It being Cambridge, I expect to be caught in a good deal of candlelight vigil traffic for the next few days.
