If you see a homeless man getting abducted, but the police cant find evidence of it doesnt mean you then have to say I was wrong, I am just seeing things.
It would be weirder if he said I withdraw my complaint because other people didnt find evidence of it. If he thinks hes heard it, hes not going to change his mind on that suddenly.
But look at this incident - Rudiger being given dogs abuse for overreacting and getting Son sent off - believes he hears multiple monkey chants in amongst literally thousands of voices from several yards away. Two weeks later a full and comprehensive investigation reveals no video, audio or human evidence to back that up ...
Let's be honest with the crowd at full volume you can't hear the guy three seats away let alone pick out what he's saying ... your analogy with a missing homeless man is just way off base ... no question that allegations go unproven every day, and no question that some are genuine ... but look at this incident.
On the basis of everything we've been told, and let's face it plain common sense, the chances that the only person in the ground, or on TV, or trawling through evidence for days, who from several metres away heard 'more than one' individual doing monkey impressions was Rudiger? that's simply no longer believable.
Rudiger knows what he thought her heard, but he was wrong ... man up and admit it.
