The White House is adding new ''pencil point'' spikes to the top of the security fence in a short-term bid to thwart intrusions at the U.S. executive mansion. Vanessa Johnston reports.
Tourists visiting the White House on Wednesday got a first glimpse of the new security measure: Sharp metal points bolted to the top of the fence. A move welcomed by many here: (SOUNDBITE) (English) TOURIST BRIAN CASALA SAYING: : "If it costs a few extra dollars to keep people out of there, then go right ahead and do it." (SOUNDBITE) (English) TOURIST KATIE KORROCH SAYING: "I think it's great. We have to protect the president of the United States, it's just a shame that we have to go that extreme." Authorities say the spikes are only a short-term bid to thwart White House intruders, and that a longer-term solution is in the works. The spikes were sparked by an incident last September -- When an Iraq war veteran carrying a knife managed, not only to scale the fence, but to enter the White House. It was one of several embarrassing breaches for the Secret Service, in charge of the president's security... And helped lead to the resignation of the agency's director. Now they're promising an entirely new fence design to begin construction in 2016.
