What about your caring IT support person that just so happens to be able to edit the logs to make it looks like the camera crashed? Or if the data somehow becomes corrupted during the file transfer process? While cameras are great people will still find loopholes and exploit them. That is the nature of man.
Conspicuous destruction of evidence is a risky endeavor. Body cameras won't make it impossible for police to get away with crimes, but they will make it much more difficult.
