MIAMI — In large and midsize cities across the country, police chiefs and domestic security officials say they have drastically increased counterterrorism operations under the assumption that a “lone wolf” or a small group of terrorists will try to strike on American soil to avenge the killing of Osama bin Laden.
Although there are no known specific or credible threats, many of the officials said they are convinced that operatives of Al Qaeda or sympathizers will be highly motivated in the weeks and months before the 10th anniversary of the Sept. 11 attacks, according to interviews with more than a dozen police chiefs and senior counterterrorism officials.
The officials said they were especially concerned that a terrorist plot would focus on a target perceived to be “soft,” like a train station or a shopping mall.
