Wire Fence around Sharm El Sheikh

Do we really need this?: "Egypt started building a wire fence around Sharm El-Sheik's tourist spots in a bid to prevent attackers from crossing into the Red Sea resort that was hit by deadly bombings in July. The fence aims to block cars from entering tourist areas except from four designated points and thus prevent possible terror attacks. It would span 20km, stands five feet high, and be patrolled by security forces. Work has already started. Once the fence is complete, access to the city will be restricted to police-monitored entry points, equipped with state-of-the-art explosive detection equipment. The opposition newspaper Al Wafd put the fence price tag at 20 million Egyptian pounds ($3.5 million), but did not say how it obtained the figure."
