Another interesting article on it:
http://motherjones.com/environment/2011/09/tea-party-gibson-guitar-wood -- perhaps inappropriately political for this forum but specifically interesting was the DOJ/DOI letter
https://motherjones.com/files/doj_-_doi_response_re_gibson_guitar.pdf as it addresses the issue of SWAT teams used in the raid (I wondered if that had been hype as the photos I saw didn't look that way - baseball caps, beige shirts, military cargo pants, and pistols - I didn't see larger weapons - perhaps I missed them?)
"Law enforcement agents are required to carry side arms during the execution of warrants for their own protection and generally wear clothing and badges identifying themselves as law enforcement. SWAT teams and similar tactical units were not used in the execution of the warrants at Gibson's facilities."
Also interesting in that letter, for those with anxiety about personal instruments: "Finally, people who unknowingly possess a musical instrument or other object containing wood that was illegally taken, possessed, transported or sold in violation of law and who, in the exercise of due care, would not have known it was illegal, do not have criminal exposure. The Federal Government focuses its enforcement efforts on those who are removing protected species from the wild and making a profit by trafficking in them."
