However, on looking closely at the photograph, it is clearly evident that the windows of the patrol car are wound up which, by extension, means the engine is running with the air conditioning on. Setting a good example for other selfish Hong Kong drivers who continually leave their engines idling when parked, regardless of the weather? Obviously not.

In addition, the police car is parked near a primary school, possibly inflicting young students with an unnecessary extra dose of pollutants. The idling engine matter should be a point of real concern and hopefully this will be addressed by senior officers when admonishing the naughty nappers.
