Who's the bully now? After claiming that his daughter Sam, 9, was bullied out of school and called a liar, Charlie Sheen has posted "a legitimate call to arms" on Twitter, asking his fans to send "a rotted egg, a roll of toilet paper, or some dog sh—" to the school "with extreme prejudice."E! News that it was "concerned" about Sheen's revenge plot and had addressed his bully accusations last year, when Sam last attended the school. "Viewpoint School's highest priority is the safety, security and education of our students. Like all responsible schools across our nation, we are concerned when any individual uses a social media forum to encourage actions that may risk the safety and security of any school, the statement read."The parent of a former Viewpoint School student who has not attended Viewpoint School since March 2012 has made certain accusations in the media. Viewpoint School first became aware of these accusations last year. Our administrators addressed the issue appropriately at that time. Our School takes accusations of bullying very seriously. For over 50 years, Viewpoint School has provided a safe and nurturing environment for our students to thrive, and we will continue to do so."
