COP THAT Some of the mainland's top airport cops were in Hong Kong yesterday for a conference on aviation security, hosted by the Aviation Security Company (Avseco) and the Airport Authority. One would expect tight security at such an event and Lai See was not disappointed. A South China Morning Post reporter got his own police escort - off the premises. Apparently, the conference was off-limits to media. DAVY COME LATELY Getting bequeathed quite by chance an unusual surname that is shared with a global rock icon has its advantages. One is never short of a chat-up line and can expect good restaurant service. The downside is dealing with the Hong Kong press corp as the boss of Deloitte Touche Tohmatsu's China practice found yesterday. Was he the elder brother of a certain David Bowie, quizzed a credulous pack. Of course, offered Peter [Bowie], but the rock star chose to join the Bowies after changing his name from David Jones in the 1960s. SORRY, MS LAM Lai See can be a suspicious sort, seeing plot and deviance at every turn. Hence when we read a rather gushing missive in this paper's letters page from Naomi Lam on her experience with the '3' phone service we sniffed, well, an affiliation. It seems we sniffed too soon and a quite reasonably outraged Ms Lam has informed us that she is not employed by everyone's favourite 3G firm. The battle for Hong Kong phone users can be dirty one, but on this occasion a contrite Lai See admits to an unhealthy dose of conspiracy fear. Happy clip viewing, Ms Lam.
