Definite Knowledge?

[so cal lurker]

After hearing about it but never seeing it, I was at a BV game last week where the shot clock went to zero as a ball went out on the baseline - but no horn. Defense wanted violation. Officials let offense inbound. Oddly, th defense, which had the three tallest kids on the court, let an offensive player run all alone into the center of the key for a lob he volleyballed in. (Also oddly, the horn didn't go off at all on the play... Making me wonder if there actually was some form of malfunction - since it benefitted the visitors, can rule out malfeascance....)
