Well that proves what? Was the area where the "boomers" were exclusive federal jurisdiction or concurrent jurisdiction? Do you even know?The Bangor Base was split into three parts. The Main Base, Core Area and the Sub Base itself. Believe you me. If you didn't have the right ID you could find yourself shot if attempting to enter the lower area where the Boomers were.
Certain types of assests are never stored in areas of concurrent jurisdiction, and I'm willing to bet those "boomers" are among those assests.
None of which changes the fact that state and local LE have authority to operate in and enforce state law in areas of concurrent jurisdiction.
