"in the past, being a police officers are the last thing young people would do"
NOT the case.
Lets just say, people who wanted to be docs, real estate sales guys etc were never on the list of people who wanted to join the force at an entry level.
However, a LOT of young men and women choose public service - they're good people. These days, they choose other disciplined / uniformed services and not HKPF.
Their education levels are on par with what their job requires. Despite what the protestors say - you don't need university degrees to patrol the streets and do their jobs as a policemen/women.
For their education levels (again - not everyone wants to or can go to Uni) the pay scales are pretty good. And keep in mind, this is a job for life - which you will not get in the commercial world.
It is the job for life thing that can be used to effectively create a working police force, or a police force that feels that they can do whatever they want because they cannot get fired.
