Rarely a night passes when my family and I are not woken in the early hours by the wailing of police sirens.
As there is little traffic on the streets at that time, is it really necessary for the police to announce their arrival in this way?
Surely the lights on their vehicles should be sufficient warning to any motorist to give way.
Also, if the officers are looking for drugs or illegal immigrants, one would imagine that their raids would be more successful if no advance warning was given. It only takes a few seconds to flush drugs down the toilet, or to escape via a fire exit.
Given all the noise people have to endure in Hong Kong throughout the day, surely we are entitled to a good night's sleep.
Perhaps the police force could examine current usage of sirens and find some way to reduce the amount of nightly noise pollution in inner city districts.
