Terrorism only works if people allow themselves to be terrorized. People like, for example, shoppers in New Haven, Conn.:
Two people who sprinkled flour in a parking lot to mark a trail for their offbeat running club [the Hash House Harriers] inadvertently caused a bioterrorism scare and now face a felony charge.
New Haven ophthalmologist Daniel Salchow, 36, and his sister, Dorothee, 31, who is visiting from Hamburg, Germany, were both charged with first-degree breach of peace, a felony.
The siblings set off the scare while organizing a run for a local chapter of the Hash House Harriers, a worldwide group that bills itself as a "drinking club with a running problem."
Mayoral spokeswoman Jessica Mayorga said the city plans to seek restitution from the Salchows, who are due in court Sept. 14. "You see powder connected by arrows and chalk, you never know," she said. "It could be a terrorist, it could be something more serious. We're thankful it wasn't, but there were a lot of resources that went into figuring that out."
Maybe there's something about New England that prevents the police there from exercising common sense (see, e.g., blinking advertisements).
Update, 15:20 CDT: Security expert Bruce Schneier has declared this the "stupidest terrorist overreaction yet."
