There are multiple sources for crime - although you'll notice the disclaimers on the sites as you can imagine the problem with trying to know everything about a place. Here's a few more sources to help you:
Also, here's the Arizona Buyer's Advisory which gives lots of links of various items you may want to check out before purchasing a home (crime, sex offenders, ... links included in there too):
Also, there's nothing like walking around the neighborhood to get a feel of it for your comfort level. Make sure you visit at different times of the day / week too. Best wishes and feel free to call or email if you want to chat about any other items you'd like more information on.

Patrick is correct, an agent cannot give you answers to this or an opinion on the area. Here is the link to crime statistics for Chandler http://www.chandlerpd.com/crime_stats.html
Keep an open mind when interpreting these statistics, i.e. is there a bar or movie theatre nearby, etc.
Also, an excellent way to see who your neighbors will be is go to the grocery store that you would use if you moved there. The people in that grocery store will be your neighbors.
Take care, and feel free to contact me for any additional information
