Does the LA Times mention that Gretna's entire government is run by Democrats?
Uh no.
No, it isn't there job to stop ANYBODY from coming in. It is always law enforcements job to protect life and what they did was reject people fleeing an oncoming hurricane.
I think the law enforcement of Gretna, at least the decision makers, should be looked at to see if they violated any laws by denying safe haven to evacuees. They put the safety of structure above the safety of human life.
