Final answer:
The claim that one would not be guilty of burglary if they entered a building with intent to burglarize but then abandoned the purpose is false; burglary is defined by entry with intent to commit a crime.
Step-by-step explanation:
The statement that one would not be guilty of burglary even though he entered a building with intent to burglarize it, if he abandoned his purpose once inside and left without taking anything is false. Burglary is typically defined as unauthorized entry into a building with the intent to commit a crime inside, particularly theft or felony. In most jurisdictions, the crime of burglary is completed once the individual unlawfully enters the building with the requisite criminal intent, regardless of whether the intended crime is completed or not. Therefore, the mere entry with criminal intent can establish the guilt of burglary, and a change of heart upon entering does not negate the burglary charge if the intent had already been formed prior to entry.
