How is something that happens in nature "supernatural"?
I know we usually don't see eye to eye, but this quote is money, lol.
You also make a good point about the whole 'getting religious' aspect. If you locked me in a cage, I'd also tell you whatever you wanted to hear to get out sooner.
Believe in God? Sure!
Worship satan? Why not!?
lol.
Back to the OP though....it's a hard case to make that more christians break the law than aetheists unless you account for the fact that there are simply more christians in the society. (This may have been addressed alreaday, but I think it's very fundamental).
Or, take the racial cross section of both groups. Most people in the US are racial minorities. Hispanic and African ethnicities being the two most common, Christianity is very high in these groups.
It's clear to see, that if the laws of the Country discriminate or are unjustly applied to these groups (which I believe there is a case to be made here), that the percentage of Christians in jail would be higher than non christians, based on the underlying demographics of the situation.
