Europeans Being Blamed for Subway Graffiti in NYC

Europeans from Germany, Italy, France, Spain, Switzerland, Denmark and Norway are being blamed for carrying out graffiti attacks on New York City's trains.
Although the vandals are aware that their works of art will be scrubbed clean within hours, they still do it and take pictures and videos to take back home with them to Europe.
Two men, one from Poland and the other from Germany were once caught with spray paint and a videotape showing them spray painting subway cars. They did time in jail briefly then never showed up at their next court appearance.
