This is a purely theoretical question. For example burglary is a crime. An attempted burglary is also a crime, but not as severe as a real one.
Getting other person's banking information (the number of accounts, the total amount) is a crime. But is an attempt also considered a crime ?
For example, if I work as a realtor. Can I call to my client's banker, and ask questions about my client's banking info (total savings, liquid assets) ? Is this legally okay ? Or do I violate any law by attempting to get this info ? The banker will most likely not share this info, but is my attempt considered illegal ? If yes, then what article of what law am I violating ?
