What term describes individuals who engage in criminal acts with a profit motive and require planning and skills?

The term that accurately describes individuals who engage in criminal acts with a profit motive and require planning and skills is "Professional Thieves." These individuals approach their criminal activities with a level of sophistication that includes meticulous planning, strategic execution, and often a specialization in certain types of theft or crime. They usually have knowledge of security systems, target selection, and methods to evade law enforcement, which marks a significant distinction between them and other types of criminals.

In contrast, robbers typically use force or intimidation to take property from others and do not necessarily rely on advanced planning to the same degree as professional thieves. Burglarizers may engage in unlawful entry but might do so with less emphasis on skill and planning than what characterizes professional thieves. Amateur criminals tend to act impulsively or without the experience and calculated approach that professional thieves employ. Thus, "Professional Thieves" best encapsulates individuals who methodically plan their criminal acts for financial gain.
