'Minds me of a C4 (UK) docco on horse racing years ago.
It went on for 90 minutes about how evil big-buck-bookies would lay more bets to shorten the odds (d'uuuh) and how awful this was and how the 'punters' were being ripped-off etc..
In the last 5 seconds they admitted that "...of course, this practice is NOT illegal and a bettor can 'lock-in' the (longer) odds when betting"
Wouldn't Walter Chronkite be proud.
