Free Speech in Greenwich (Except for Environmentalists)

Greenwich police say they arrested three environmentalists last week because they were afraid the fake "wanted" posters that the three were putting up near the home of the JP Morgan Chase CEO would alarm local residents. According to yesterday's New York Times:

the department had concluded that the posters "could be cause for alarm" because passers-by might think criminals were at large.

Does that make even one ounce of sense? Would anyone living in Greenwich in 2005 think that a "wanted" poster on a utility pole was for real? I wonder when the last time a real "wanted" poster was displayed anywhere in Greenwich besides the post office? Here's how the Times describes them:

The posters were designed as old-fashioned "Wanted" posters, featuring photographs of the chief executive, William B. Harrison Jr., referred to as "Billy the Kid" in the accompanying text. The posters criticized the bank for what was described as its "reckless investment in environmentally and socially destructive projects in dozens of countries," and urged anyone who spotted Mr. Harrison to "ask him to do the right thing."

The ACLU of Connecticut seems to be deliberating about whether to take the case.
