From a psychological standpoint, this argument makes sense. I think that they way some of the protesters are acting, (screaming insults and coming right up to the edge of the driveway), puts the Anthonys in a position of "us against them", which takes the focus off of the fact that Casey knows what happened to Caylee and isn't talking.
People who have no consideration for the rest of the neighborhood are just plain rude and obnoxious. No one looks intelligent when waving a half-smoked ciggerette in someone's face and having a conniption fit.
Quite frankly, the Anthonys have shown much better restraint than I would if someone were loitering on my street, acting like fools. Maybe the neighbors should all tune their stereos to the local Christian or classical station and turn up the volume. That would get rid of those street-trollers pretty quick.
The Anthonys are wrong for allowing Casey to enjoy the comforts of home while not cooperating with police. If she were my daughter, she would not be allowed home until she told all she knows. The protesters are doing nothing but creating a public disturbance, and that's wrong too!
