Maybe gunshots were heard by the rescuers - there have been 2 reported shootings involving law enforcement and looters but no recorded attacks on rescuers - but is it a convenient excuse to hide their lack of ability to rescue the people there? Shooting is preventing rescue efforts for all of the city?

Why do I think this? I know the info-marketing game. Sean Hannity is closely linked to Karl Rove's office. He gets talking points from that office daily if not hourly.

All Hannity did on his radio and television show today was discuss how looters were halting rescue efforts because police and National Guard units were being diverted to stop the lootings.

Hannity would do all he could to divert the discussion to this "talking point" when the issue came up that there was no rescue effort visible.

That is how the Bushies are going to spin why there was no initial rescue effort - the looters were shooting at the rescuers - to hide their lack or resources and competence.
