There's a time and a place for everything

Okay, there's not necessarily a time and a place for burglarizing cars, but doing so outside of the courthouse where you're answering to theft charges is probably one of the worst times and/or places for that kind of thing:

Police say a Connecticut man who appeared at a courthouse to answer a larceny charge broke into several cars in front of the building, took a GPS unit and inadvertently tried to sell it to its owner.

[...]

When he tried to sell the GPS to its owner, an argument ensued, and a bystander called police. He has been taken into custody by judicial marshals.

The article mentions that this is his 40th arrest. I guess you just stop trying after a while.
