Wow...pretty stupid IMHO...yes it may hurt Glocks image, but it looks like greed plain and simple, specially the point of the two Glock guys wives making fake companies to hide the bribes....
Only getting charged with 21 counts of wire fraud and money laundering isn't great, but it beats 14,000 counts of federal tax evasion they could have gotten because of the 10% FAET (Firearms and Ammunition Excise Tax) that was circumvented.
