I completely agree, but to expect every single officer to devote a lot of effort, to that extent, into the role is pretty far fetched.If you implement that system it has to be mandatory or there is no point what-so-ever having it. If you divide the department into two parts where you have one under-trained or differently trained part that does not know proper procedure and then another one that went through a training program it won't help at all. As you will have people running around not knowing what to do, just like now.
Making them non mandatory solves a lot more issues than it causes, they can all award a certificate or insignia of sorts to actually symbolize that Officer being qualified in the region, which like I said beforehand, divides them from the Officers that'd rather just relax and play the server in a more laid back way. It means the PLPD supports more styles of play which is exactly how it should be.
