Intelligence that first suggested an attack may have brought down a Russian passenger jet over Egypt last week largely justifies the mass surveillance carried out by U.S. and British spies, experts said Friday.

While accumulating massive amounts of intercepted telephone and electronic communications and satellite imagery can hardly ever prevent an attack, it can help to shed light afterwards on what happened, they said.
