Some people are just nuts! Some people are just as murderous in their hearts as they claim Casey Anthony is...especially if they have the energy to go out and taunt her.
Even if they did have strong feelings against her, they could have still gone about their daily lives minding their own business.
This whole thing is a media-created circus.. People are getting more brazen..more outspoken. That's scary when people do it without really knowing what they're doing and without having a good reason WHY they are doing it.
