It's worth pointing out that Henry E. Juszkiewicz, Gibson's Chief Executive Officer, is a donor to a couple of Republican politicians. According to the Open Secrets database, Juszkiewicz donated $2000 to Rep. Marsha Blackburn (R-TN07) last year, as well as $1500 each to Sen. Lamar Alexander (R-TN). Juszkiewicz also has donated $10,000 to the Consumer Electronics Association, a PAC that contributed $92.5k to Republican candidates last year, as opposed to $72k to Democrats. (The CEA did, however, contribute more to Democrats in the 2008 election cycle.)
When warrants as ridiculous such as these are issued and executed, there appears no other reason than because the company or individual at hand is being targeted, not because there is any sort of wrongdoing. As a company, Gibson is a legendary. They've done nothing wrong, except, apparently, deigning to have a Republican CEO.
The plot thickens, however.
One of Gibson's leading competitors is C.F. Martin & Company. The C.E.O., Chris Martin IV, is a long-time Democratic supporter, with $35,400 in contributions to Democratic candidates and the DNC over the past couple of election cycles. According to C.F. Martin's catalog, several of their guitars contain "East Indian Rosewood." In case you were wondering, that is the exact same wood in at least ten of Gibson's guitars.
