I heard a story on the radio about a local teacher who was fired when a student accusing him of having a relationship with her. Due to the seriousness of the charge, and not necessarily the burden of proof, the teacher’s life was put into peril.
I decided I needed a alibi to prove my action, for right or wrong. My digital witness is a Olympus VN-6200PC digital voice recorder. I carry it everyday and it is recording the whole time. I have to dump the memory onto my computer every couple weeks, but the space it uses is negligible. I also have some rechargeable AAAs that get replaced everyday.
