There were several good responses written on the wall. I tried to take a picture of this one, but it didn't turn out that great:
The response reads:
All hail the new king of a-hole tots... Kief! This genius quotes Warner Bros. films on the walls of small businesses... Meanwhile - Google, Starbucks, and the banks remain untouched! What a brave guy! You're like the next Banksy, Bra. I wish Exit Through the Gift Shop never came out.
Looks like someone suspects local tagger, Kief, of the crime.
