There are some sites you can check just so you can see for yourself. And...just for comparison, enter other zip codes and cities.
Trulia has its own site where you can look http://www.trulia.com/crime/Oakland,CA,94601/
Crime watch http://gismaps.oaklandnet.com/crimewatch/
Spot crime http://www.spotcrime.com/ca/oakland
And.... you can drive around the neighborhoods during the day and the night, too. Bring a friend,
Good luck to you.
