Such a policy is dangerous to freedom of expression, providing a license to suppress speech deemed provocative, and to public safety, encouraging violence aimed at eliminating offensive messages.

WMATA said it was indefinitely postponing placement of the AFDI ad because of concerns about "security and safety." Specifically, as U.S. District Judge Rosemary Collyer noted in an October 12 opinion explaining why she had overturned the transit authority's decision, "WMATA cited two ways in which the ad could threaten public safety: (1) inter-passenger disputes on subway platforms that could result in passengers falling into the tracks or (2) a terrorist attack."

Collyer mentioned no evidence supporting the first fear, which gives new meaning to the phrase "third rail of American politics."
