I think the best way to get crime rates it to go to the local police dept. They will print out acitivity in the last 6 months for you. I dont trust websites that offer similar situation I prefer to go to the direct source. You can also ask a police officer in the area.
Hope that helps.
If I can be of further assistance please contact me directly at 561-868-0591
