Since crime can happen in any zip code, a licensed Realtor can not comment on an area being "safe" or not.
I have a link on my website that people have told me has been very helpful to them. You can compare zip codes and you'll see the demographics, crime-statistics, etc. Hope this is helpful for you:
Go to www.MckinneyRealEstateInfo.com, then go to "insights" and from there you can compare zip codes.
