I too experienced this in C section, which is by my own admission, not one of the noisiest sections of the main stand - unless we aren't doing too well of course which was the case yesterday. I heard a lot of shouts from the same few individuals I think and it was one of these shouts which provoked a response from CC himself, during a quiet period of play on the field - a response which was a bit x rated and indeed easily audible to the front sections...
Now I can't condone the idiots who don't get vocal unless they're having a go at ICT staff, but CC has to watch how he handles this type of thing in the future or it will further alienate him from some already indifferent sections of the home support.
