The fun of the whodunit capers of mystery shows, even if they’re one of CBS’ dime-a-dozen police procedurals, is trying to match wits with the detective to figure out who the guilty suspect is. For tonight’s episode of Hawaii Five-0, CBS letting viewers vote online and using Twitter hashtags to determine what the ending of the show will be.

The vote, which CBS refers to as being a television first even though I understand that the WWE has being using Twitter to book parts of their show for a couple of months, will take place during both the east and west coast airings of the show. From 10 PM (both ET and PT), viewers can vote for one of the three possible suspects as having murdered tonight’s victim. The most popular selection will be the guilty party and that ending will air. CBS says they’ll put all three endings online so you can watch them afterwords.

Being a bit of a geek (hence why I created this site), I have to ask: Which is the canon ending? As there will be two votes, it’s possible that two different endings will air. We could be left with a situation where the same investigation with the same sets of facts result in two people having committed the same crime. Should such a situation arise, will the writers/producers declare one “guilty” party the actual killer or will it not actually matter because story isn’t really the strong point of police procedurals so who really cares?
