You can feel Katrina's devastation from all angles in two strong documentaries airing Tuesday in unfortunately simultaneous time slots.
One provides the close-up immediacy of a "Cops" ride-along, tracking two New Orleans street officers trying to keep order in what looks like some post-apocalyptic landscape, with no supplies, no police facilities, no homes of their own, and no time off to process it all.
The other is a documentary distillation of the entire event, laying out a two-hour blow-by-blow account of what happened where at every step of the storm. "Inside Hurricane Katrina" is another of National Geographic's just-the-facts-ma'am roundups. Like August's "Inside 9/11," it seeks to comprehensively outline a clear understanding of how the hurricane wreaked such destruction, both physical and personal.
