Realistically I'd imagine Suarez wouldn't have been found guilty.
The decision was based the "balance of probability" which is a notch lower than the criminal standard of "beyond all reasonable doubt".
That's not to say he wasn't guilty - just that it would've been challenging to prove.
Worth noting that it's not quite one man's word against the others.
Although there was no lip-reading evidence presented the video footage did help the panel sense-check each player's account of events and decide wich account better fits with their demeanour & physical interactions.
