Go to the local police precinct and ask them. You can also Google crime statistics by zip code and get a lot of good info. Spend some time in the area and talk to the people that live there. Go there late at night and see what's happening. Also speak to store owners.
In the end it is a matter of opinion. I think just about anywhere in Brooklyn is safe, that's my opinion.
