Career criminals react to their environment and circumstances in order to establish whether there are increased risks to their criminal business, supply chains, cash flow, or liberty. Simultaneously, they seek to identify any potential opportunities to further their criminal endeavors.

The fact is successful criminal businesses adapt in the same way as successful legitimate businesses. It is said a business that is not growing is in effect a business that is dying. Just as big businesses change, so do criminal enterprises. Change has seen some established business and brands all but disappear; technology changes consumer demands and expectations. Nokia did not move quickly enough to smartphones, Kodak was helpless against the evolution of the digital camera, and presently, synthetic drugs are changing the criminal marketplace.
