Professional Burglars

The definition of burglary (break and enter) is the breaking into and entering a place with the intent to commit an indictable offence, and is considered much worse than theft because it involves entering another's home. Because it is a much more serious crime it has been long associated with professional thieves who carefully learn their craft. 
Some of the qualities a financially successful professional burglar include someone who has mastered the skills of their trade and has learned to spot environmental cues that nonprofessionals would usually fail to notice. Most burglars prefer to victimize commercial property, the most favourable target being retail stores rather than private homes because of its accessibility and easy ability to plan a burglary on. For example, retail stores display all their items along with their prices making it easy for a burglar to know exactly what they're looking for and how much they will get for their stolen items. 
When burglars approach their job, some of the major techniques they use include... Targeting acquaintances and drug dealers, use tipsters, stake out residences , working in groups, and disposing of goods through a professional fence or pawning the goods. Some burglars also hit the same target more than once because of their previous experience with the target and because they now know the layout of the house, goods they may have missed, and because they are essentially sure that the target will result in a successful burglary again.
For a burglar to become lucrative in this career they must develop four key requirements of the trade: 1) they must learn the many skills needed to commit lucrative break and enters. 2) the good burglar must be able to team up to form a criminal gang. 3) the good burglar must have inside information. And 4) the good burglar must cultivate fences or buyers for stolen wares. Most learn these techniques through from older, more experienced burglars .
