A Budding Banksy in River Forest?

Street art or vandalism? 

Authorities chose vandalism. 

Augustus Federici, 19, of River Forest, was charged with criminal defacement of property after police identified him as the vandal behind several instances of graffiti at various railroad overpasses throughout the village. Police spotted Federici around 2:15 a.m. Monday and "discovered spray paint and markers in the backpack," according to a police report. 

"For what it’s worth," Deputy Chief Craig Rutz said, "the officers indicated he was very cooperative and took responsibility." 

At least one of the works, photographed here at the west-facing railroad overpass at Lake Street and Park Avenue, appears to be styled after British street artist Banksy.

So we ask you, readers, is this art or vandalism? And does it matter if the work is good or bad?
