I doesn't seem to me that having what I consider a reasonable retention period would be too bad, where "reasonable" is on the order of 7-30 days. If a person hasn't reported a crime within that time, then the tapes (or drives or whatever) are wiped. Any shorter than 7 days, and you risk the person being in a state of shock/in a period of "I should report this - no, wait, I don't want any trouble - no wait, it could happen to other people," etc.
