Last month, local police ticketed a teacher named Kevin Egler for posting a sign in a public garden that read “Impeach Bush.” Police ticketed him for unlawfully advertising in a public place. Egler said that when he was stopped, he asked the police officer how his sign differed from realtors posting signs on public property saying, “This way to the house for sale.” He said the officer asked, “You don’t know the difference?” but then the police never explained what the difference might be.
