I think this is one of the most ridiculous questions I have ever read.  What are you going to do..have people fill out a form before they are ALLOWED to have children?  This is stereotyping.  Some children follow in their parents footsteps and some DON"T...You obviously dont get out much.  Crimes are committed from folk from alll walks of life stupid.  Do you not watch the news?  Millionaires commit murders, people WITH money steal..Single parent homes dont usually start out that way...MOST times a loser decides they want out and leave and the single-parent MOSTLY women stay and hold it down as best as she can...I know cause I AM A SINGLE PARENT of 4 BOYS (7-18)  None of my sones have been arrested for anything.  My 18yr old son is going to college this year so dont talk to me about control.  Did you not just see that Dana Reeves died of lung cancer and she was a non-smoker so what now?  IDIOTIC people shouldnt be allowed to have kids and I hope you never do because ignorance kills ya loser.
