Obama has banned deepwater drilling (I can buy that at a stretch, but I'm not convinced he's done it for the "right reasons") and the Senate is already hearing testimony.
It might be reasonable - we aren't experts so it's impossible to know if this incident is part of a wider risk. But this big thing about banning it till 2011 is political posturing. Suspend things, let the experts review and decide on the safety, then make a decision.
