Maher on Anderson Cooper

Bill Maher appeared on Anderson Cooper 360 last night, and directly took on radical Islam, appealed for gun control in the wake of the revelation that suspected terrorists can still buy guns, and shot back at the right-wing, who are claiming that the Gulf of Mexico oil spill is "Obama's Katrina", even though it wasn't a natural disaster and Obama didn't receive constant prior warnings, days in advance of the disaster.
