The Governor of Maine, Paul LePage, is a CCW permit holder himself and so no doubt understands why making such records public is a bad idea. From Seacoast Online:

The issue was pushed to the forefront in Maine in February after the Bangor Daily News made a state Freedom of Access Act request for information on concealed weapons permits issued by the state.

The News’ action caused an uproar among Maine gun owners and legislators, who worried that such requests would violate the privacy of law-abiding gun owners. The newspaper said it never intended to publicize personally identifying information about the gun owners.

The bill sponsored by Republican Rep. Corey Wilson of Augusta was scaled back to allow aggregate information about permit holders to be released, but no personally identifying information. Wilson was relieved by word the governor would sign the measure.

Well, more common sense here than in Nebraska.
