Learning how to avoid being a victim of crime is an important life skill. At school you learn to lock your locker securely and not allow other people to see what the combination numbers are. You would not leave an expensive or favourite coat hanging up unwatched in the cloakroom and you would not broadcast how much money you were carrying in your pocket.
As you get older, you learn that when you hear about a 'too good to be true' deal, it is most unlikely to be true. You know that someone calling at your door unexpectedly might not be who they say they are, and if you buy a gold watch in a street market, the gold might wear off in a week or two. Perhaps you learn some self-defence, carry pepper spray, install a burglar alarm or get a guard dog. You might simply avoid people and places where you feel at increased risk. Although it is always possible that you could become a victim of crime, there are some basics you can do to minimize that chance.
