CNN posted a new article detailing the highly-skilled countersniper unit, and the article also mentions how many security personnel will be out in force tomorrow.
On Tuesday, in addition to the snipers, an estimated 8,000 police officers will be on duty, along with almost 1,000 FBI personnel, Transportation Security Administration screeners and others, including 10,000 National Guard troops. The Department of Homeland Security has said that another 20,000 members of the National Guard are being held in reserve.
“I think we are ready,” said Homeland Security Secretary Michael Chertoff. “I don’t anticipate anything disruptive. Part of my job is to hope for the best and plan for the worst.”
