FL Guide & Tourney Pro Sentenced for International Weapons Trafficking

From this story in the Orlando Sentinel:
A local bass tournament pro pegged by federal agents as the center of an international firearms-trafficking operation will be sentenced in Orlando federal court today. Hugh Crumpler III, a well-known Central Florida bass fishing guide, pleaded guilty in June to charges of unlicensed firearms dealing and possession of unregistered firearms. He faces up to 15 years in prison.

__The 63-year-old told federal agents he started buying and selling guns as a hobby, which eventually morphed into a business. Crumpler, of Palm Bay, admitted to selling guns and knowing most of them were going out of the country to places like Honduras. Guns linked to Crumpler were being tied to crimes, including a homicide in Colombia, records show. Federal agents say Crumpler mostly bought guns that are the preferred weapons of drug cartels in South and Central America, including a semi-automatic handgun that fires a rifle round capable of penetrating bulletproof vests. Crumpler is slated to be sentenced at 9 a.m.

So that begs the question: what are the signs that your fishing guide is actually an illegal weapons smuggler? Is it the fact that you're fishing out of a cigarette boat instead of a bass boat? Any other suggestions that might clue you in?
