ON Monday, amid the pageantry of the Royal Hong Kong Police Force's 150th anniversary guard of honour at City Hall - as polished heels snapped together and sunlight sparkled off the shine of bayonets and ceremonial swords - few would have bothered to contemplate the enormity of the challenge awaiting the territory's law enforcers.
When the Commissioner of Police, Li Kwan-ha, traipsed to Queen's Pier to greet the Governor, Chris Patten, to help celebrate this magnificent moment, it was almost incongruous to consider that, in a few years, all this regalia and order may have vanished.
However, inside the cosy, clustered police ranks, a revolution is unfolding.
In the past 18 months, every aspect of police life has been scrutinised and audited to determine the efficacy of management style and substance.
And it seems, at long last, that a progressive school of thinking is seeping into the upper hierarchy; a philosophy which says - perhaps unremarkably - that police should be patrollers and peace-keepers rather than pen-pushers, drivers and station guards.
But it is not a movement beyond being resisted.
Because, if it is considered reform should prevail over accustomed practice, some in the force have much to lose.
