As a matter of fact, the 'best' wood for bows, Pernambuco (        Caesalpinia echinata) is listed by CITES in category II, 'might become endangered' and subject to scrutiny...meaning it will probably end international trade.
So far, Ebony is NOT on the list, and only Bolivian Rosewood is in category I. 2 other rosewoods (from Guatemala) are listed in category III, meaning that individual states may require permits to obtain specimens.

I am not sure what triggered the raids on Gibson and under what authority.
