I disagree since many of the CRIMES are based around religious motivations. If an atheist practices NAP (Non-aggression Principle) then I know they'd be less likely to commit crimes.
NAP if you are unfamiliar with it (if you are my apologies) basically says that a person is free to do as they like with their body and property until they infringe upon the rights of another or harm another.
AKA - no victim - no crime
EDIT: I don't completely identify as an atheist. Simply because there are two possibilities I'll never be able to prove. Either 1) There has always been something here... then I'm fine with atheism, or 2) Something caused the catalyst to create this all... which makes me a Deist (not to be confused with Theist). I don't believe any fellow human being is going to be able to tell me the secrets of the universe. I don't believe in revelation. I don't believe in ANY written books claiming to hold the answers. I actually see that as arrogant and controlling. I instead view it as a constant adventure and hope I find out.
I've personally witnessed more evil done by so-called Christians I've known in my life than I have other things. They often forget a couple of really important things. (My mother is very Christian by the way)
The Christian God gave mankind Free Will. So what gives other humans the right to try to force and take that free will away that was God Given, and to condemn and persecute human beings for exercising free will? Furthermore, if a human speaks to me claiming to know the answers and telling me I am damned if I do not accept Jesus into my life. I ask what happens to the people that don't encounter a missionary to ask them this question. I've often been told that God will put the question to me himself at judgement. I then have to wonder how many people my fellow human beings are damning by putting a question to others and expecting them to believe it when they'd be far more likely to believe it if it came from God him/herself.
Ultimately I consider all written religions to be like a Santa Claus for adults. That doesn't mean I have no sense of morality or ethics. It simply means I am responsible for my choices. If I hurt someone that is on me. If someone is hurt due to my inaction when I could have helped, that is on me. I can't blame it on being the will of God. I also don't fail to take action and hope God will fix everything. If there IS a God (for me Deism) out there then I guarantee you he is not as arrogant and petty as they portray him/her in these books. That is the hallmark of human created speculation that people decided was fact to me.
