This photograph shows construction of the new security fence which is doubling in height from 6ft 6 to 13 feet - old fence on the left, new fence on the right. After a recent number of breaches, resignations, and embarrassments for the Secret Service, it was clear the old fence was inadequate. The new one is far stronger and incorporates intrusion detection technology. The serving president is the only person required by law to be protected by The United States Secret Service whether he/she likes it or not. For all other protectees, such as ex presidents and presidential candidates, security is optional.
