Very dysfunctional families often isolate themselves from others to hide their dysfunction. Whether it's something as ignominious as incest or domestic violence, or as insidious as addiction, or maybe just run of the mill squalor, the family members know that their lifestyle is aberrent or off-kilter and seek to hide the flaws. As much as Cindy tries to paint a pretty picture of her family life, she surely knows that it won't stand being held up into the light of day. She tried to ignore the obvious signs of an advanced pregnancy at a family wedding. How she must hate that the truth about George's money mishandling and KC's thefts from family and friends are now common knowledge. The Anthony freak flag is flying high now, but I'm sure even back in the day others were aware something was amiss. Why else did Cindy have only once a year contact with her brother Rick? And aren't George's parents now in FL too? Where are they in this debacle? They too lost a family member, and yet not a peep is heard. There are reasons; we've heard about the plate glass window. What else transpired to isolate and alienate?
That being said, I'm sure that many people would have been willing to offer support but for th fear of being labeled a Kool-Aid drinker too. Susan Smith's mother found comfort in her church and in her community because she acknowledged the horror her daughter set forth and her own role in it. She still supported her daughter without making ludicrous claims as to her innocence. And even Susan admitted her deeds, albeit after a few frantic days of denial.
People champion underdogs. People understand accidents; they can learn to forgive flashes of violent anger or even callous neglect if there is sincere regret and a willingness to accept responsibility and understand that there will be a price to pay. People don't like being played and manipulated, having their heartstrings tugged for LOLZ, and being made to look like a patsy. The Anthonys refusal to face the mounting pile of evidence that KC is guilty has cost them community support, and may wind up costing KC her life.
