Cellphone Taping a Classroom Threat

The article I read was about how teachers are being taped with camera phones while lecturing in the classroom.  From the article all of the teachers were being taped without their knowledge or consent.  This to me is not acceptable and in the long run could maybe hurt more than just the teacher's ego.  It said that some students spent days taping their teachers and they're putting ellaborate videos together.  This is a huge problem.  In one aspect I think how can the teacher have this going on in his or her classroom for so long and not know.  These teachers need to be more aware of what is going on in their classroom.  It worries me that this is going on because what else is the teacher not aware of, students could be texting or talking on the phone and the teacher has no clue.  I feel that this is not a positive thing in anyway and should be handled by both teachers and administrators.  Some students even went as far as to add sound effects or music to the video to make it funnier and then put that on youtube.  People could see this and then call the school and get the teacher in trouble for something that parents found inappropriate even if they didn't get the whole story.
