Cameras in the classroom

As promised, here is my follow up on whether or not cameras have ever been put inside of an actual classroom. According to CNN.com, “A school district in Mississippi (Biloxi) was one of the first districts in the nation to install cameras in every classroom. There are more than 500 cameras in district schools and they are being used to keep track of both the hallways and the classrooms.” According to the article I read, it seemed like both the teachers, students and the community were all in support of the installation of these cameras. The only problem that I saw was the fact that they didn’t have the ability to capture sound.
It seems like other school districts that have tried to do this have had it shot down due to two major reasons; issues of privacy or funding. I can understand and appreciate the issue of invading someone’s privacy by the installation of cameras, but this isn’t someone’s house. Numerous corporations have cameras in their buildings to watch what is going on. They are there to protect the people who are working there and to ensure that if something happens, someone knows about it. The way I look at it is nothing should go on in the classroom that a teacher shouldn’t be willing for someone to see anyway, so if the funding is there I think the cameras should be as well.
