I know, you believe it is more likely That the nice man who lives down the street, has lived in the neighborhood for many years, known by his neighbors, is self-employed, no history of any thing but 1 DWI, who has some porn in his house accessed via computers, that mostly is his son's, is the KILLER.
You believe that the parents that have lived their 4 years, and no one in the neigborhood seems to know, whose kids run wild without supervision or concern, who do drugs, who do not have a NORMAL FAMILY LIFE, as they have SEX with ANYONE THAT CATCHES THEIR FANCY, WHO invite total strangers back to their house late at night to do drugs and have sex, who do not check on their children DURING THE DRUGS and SEX, Even when alarms indicate someone has been going in/out of their house, when they find doors open that shouldn't be, YEP, They are the perfect parents who are totally innocent. NOT a REASON in the world to suspect them or any of the SEX/DRUG crowd that was at their house that night.
If this is what you really support, Kim, I just don't understand where you are coming from.
