Parisians brace for Olympics opener, unprecedented security

The streets of Paris are crawling with soldiers and police. Parts of the city are off-limits, including much of the Seine river. The "City of Light" is on maximum alert to protect Olympic athletes and fans from terrorist attacks. For some locals, the measures are choking them financially. Others are finding an odd peace, as some streets become deserted. As for tourists, they're just trying to get to the Louvre. The World's Gerry Hadden reports from Paris.
