Thanks for this clear info. I think others have posted that the easement is not private property, even though typically the landowner takes care of the patch of lawn on the easement in these kinds of residential neighborhoods.
Even though the protestors are not trespassing (if they are, indeed, staying off of the private property), I don't think anyone here would be comfortable with a bunch of people standing/sitting/yelling on the sidewalk in front of their house. It is quite invasive. If a strange man, for example, came and stood on the sidewalk in front of your house with a sign about your religion or about the kind of car you drive or whatever all day and most of the night for a few nights, I imagine most everybody would call the cops pretty quickly and see what could be done--even though he'd be within his legal rights on public property (unless there are some loitering laws no one is bringing up).
Now, I know that many will chime in and say that the A's don't deserve anything or they don't deserve anything more than the respect due to the very edge of their property. While I agree technically--because I recognize and appreciate the right to assemble on public property--I disagree personally, because I don't see what the protestors are doing as helpful here. They seem to be making a spectacle and I don't think they will contribute anything positive to this case or to justice for Caylee, which is what this should be all about.
I don't think that CA is going to break because someone has a doll with a sign in its hands, or because someone rings the doorbell and yells at her or her mother; if anyone breaks, it will be one of the family members, and it won't be the kind of break that contributes to the case, but the kind that is an unfortunate result of flared tempers, stress, strangers yelling at you, and consequent altercations. Sadly, IMO, that's what we're looking at, and some people seem to be hoping for.
I just hope there's a resolution to the case soon so that justice will be served.
