Need to go back to law school and study the basics. A robbery takes place when stealing involves physical force or fear. Burglary occurs when something is stolen without physical force or fear. You can walk into an unlocked house or break a windows to get in and it is still burglary. When you threaten or use physical harm, you are robbing.
Take for example...a bank "Robber". He didn't break into the bank to steal...he used physical threats to steal the money.
Now...back to topic....I'm going to burgle mobi to my heart's content.
