A lot has been said about how ugly and mean-spirited the protestors were. I totally agree. I had never seen anything like it, ever. At first I thought maybe it was because it was so odd to have the family of a "missing" child also be the same family as the person who was the suspect. But I really think now that had nothing to do with it. I think the public would have pretty much left them alone if they had behaved differently from the beginning. And they didn't start showing up en masse until after the Anthonys themselves had appeared on the media and shown their true colors.
From the very beginning I think the Anthonys behavior to the media was like an engraved invitation to angry nutballs. They snapped at reporters that the smell in the trunk was pizza, they got angry and yelled that the human remains in the trunk was somebody else's body. CA got on national TV and said, when asked pointedly if her daughter might be involved, that if Caylee was not found soon it would be the media's fault, she accused people of putting nails in her coffin. Their behavior toward normal questioning of their daughter's puzzling, bizarre and outrageous behavior was to defensively and angrily insist she didn't really lie to LE, that it was LE that was railroading her and not really looking for Caylee, that she was the mother of the year. They were told to get off their butts and look for Caylee.
I think the combination of their self-righteous and belligerent behavior toward the press (particularly when contrasted with some of the hypocrisy they began to show early on) if questioned at all about their daughter's strange behavior and angry insistence that early evidence was false and meant nothing acted like an emotional MAGNET and drew all kinds of people who were as negative and psychologically dysfunctional as they are. It made all kinds of normal people upset because they saw it as inappropriate and unnecessarily hostile.
I don't condone anything the protestors did, and think they are a hot mess, but I don't believe they would have ever showed up or even been attracted to the case like moths to a flame if they had not sensed at some level kindred spirits in the Anthonys. Anger and high drama attracts anger and high drama - and it brings out the worst in those who draw near.
Lois originally contacted CA, and CA encouraged a relationship with Lois' granddaughter and her own daughter. She did not turn it down because she apparently felt it would benefit KC in some way to have a young child on her side. KC was not supposed to have any contact with the public at that point, so imo, CA totally asked for that too because she didn't have the sense not to exploit a child for her own benefit. The fact that KC and Annie caught CA on KC's computer emailing with KC's name when she stayed overnight made me think that CA may have been the one encouraging that on KC's behalf.
As usual, the Anthonys stoke the fire and then complain when the flames get too high and the air gets too hot. And when the fire dies down of its own accord, they are off with their "friends" to find new ways to get in the limelight.
