I Visit the Channel Gallery

As sure as the river runs dry - once the flow of water in the channel has come to a stop, the graffiti-iti make their appearance. Their canvas, those walls of concrete. Mostly what they leave behind, besides the great quantities of trash (sighhhhhhh), are scrawls and scribbles and, for some reason I can't quite comprehend, giant penis's. There always seems to be one person, though, who raises the game to a different level. 

The question I am wondering, the local constabulary and perhaps, considering where the gallery is located, their federal counterparts as well - is it a self-portrait?
