NEW ORLEANS  For weeks, Gov. Bobby Jindal of Louisiana has attacked BP and the Coast Guard for not having adequate plans and resources to battle the oil spill.

But interviews with more than two dozen state and federal officials and experts suggest that Louisiana, from the earliest days of the spill in the Gulf of Mexico, has often disregarded its own plans and experts in favor of large-scale proposals that many say would probably have had limited effectiveness and could have even hampered the response.

The state’s approach has also at times appeared divided: while some state officials work alongside the Coast Guard and BP every day, others, including the governor, have championed a go-it-alone approach.

Such a stance is popular in a place justifiably skeptical of federal disaster response after Hurricane Katrina. The federal response, at times slow and disorganized, has been a matter of grave concern to this state, with its fragile and complicated coastline.
