In burglary someone enters your home/business and steals from you.
In theft something is stolen (example :pickpocket, shoplifting, purse snatching)
Larceny is more common in court reporting as there are charges on either petty and/or grand larceny. It gets complicated once the courts get involved. (Surprise!)
Reporting on police activity is mostly concerned with burglary and theft.
The more experienced reporters are generally sent to cover court proceedings, trials etc..
