During the more-than four years of Israeli-Palestinian violence, suicide bombers, like those that carried out the attacks on London's public transit system on Wednesday, July 7, 2005, have killed hundreds of Israelis, forcing the country to develop systems to counter them and turning public places into heavily guarded compounds. In Israel, guards with metal-detecting wands frisk restaurant patrons, bus stations have airport-style X-ray machines and the public has been educated in how to spot potential suicide bombers.
