Whole of Hong Kong must take action in response to attack on Kevin Lau
Mike Rowse says twisted attempt to instil fear cannot be allowed to undermine our core values

There is a line of thought in military circles that you do the enemy more harm by injuring one of his soldiers rather than killing him outright.
A dead soldier can be left on the battlefield where he fell, and his body recovered later when it is safer to do so.
A wounded soldier will cry out for help and his comrades will instinctively want to rush to his aid, often putting their own lives at risk.
In a similar vein, terrorists sometimes set off a small bomb first to injure a few people, allow an interval for rescuers to run forward to assist the fallen, then set off a larger bomb to kill everyone.
Twisted thinking, but effective if your aim is to inspire fear.
Next time - and there is always a next time - even the well-intentioned will be slower to help. The fact that such tactics are often pursued in the name of religion is further evidence of just how mentally sick these people really are.
