CNN Doubts Need For National Guard In DC--They're Walking Around, Not Doing Much

On CNN This Morning, CNN senior reporter Isaac Dovere questions the need for National Guard troops in Washington, DC:  "I was walking around Washington. Of course, the National Guard deployment here for months, and it's been extended. "And just troops with their weapons out walking the streets, four of them at a time, walking around, didn't seem like they were doing really much of anything, except that we are now being made used to every day more troops on the streets of more American cities."
