“the absence of an ‘international standard burglar’, the nearest I know to a working classification is one developed by a U.S. Army expert [118]. Derek is a 19-year old addict. He's looking for a low-risk opportunity to steal something he can sell for his next fix. Charlie is a 40-year old inadequate with seven convictions for burglary. He's spent seventeen of the last twenty-five years in prison. Although not very intelligent he is cunning and experienced; he has picked up a lot of ‘lore’ during his spells inside. He steals from small shops and suburban houses, taking whatever he thinks he can sell to local fences. Bruno is a ‘gentleman criminal’. His business is mostly stealing art. As a cover, he runs a small art gallery. He has a (forged) university degree in art history on the wall, and one conviction for robbery eighteen years ago. After two years in jail, he changed his name and moved to a different part of the country. He has done occasional ‘black bag’ jobs for intelligence agencies who know his past. He'd like to get into computer crime, but the most he's done so far is stripping $100,000 worth of memory chips from a university's PCs back in the mid-1990s when there was a memory famine. Abdurrahman heads a cell of a dozen militants, most with military training. They have infantry weapons and explosives, with PhD-grade technical support provided by a disreputable country. Abdurrahman himself came third out of a class of 280 at the military academy of that country but was not promoted because he's from the wrong ethnic group. He thinks of himself as a good man rather than a bad man. His mission is to steal plutonium. So Derek is unskilled, Charlie is skilled, Bruno is highly skilled and may have the help of an unskilled insider such as a cleaner, while Abdurrahman is not only highly skilled but has substantial resources.”
