The problem I see with the police, and I have seen for years now, from both the perspective of the police, constabulary command, random civilian, organized gang, and whitelisted rebel, the quality of the police as a whole brings it down.
Now dont get me wrong, I have seen some highly skilled and talented individuals inside the police, often doing well in that career. However that inst the bread and butter of the police. They are not the lowest common denominator. The most common police are PC, SPC and SGT. The problem remains that the police recruit people who often have limited experience with Arma, new to the community, or are not familiar with skills needed to go around as an officer.
Now this does not have to an issue, however the training that they receive to get past CSO and PCSO is limited, they do not produce top class officers. Most of the time the top class officers are already made prior to joining, or they learn on the job as an SPC. Now I am not saying that the reason the police do not perform well is due to academy, it isn't. Its a video game at the end of the day, and they can only go around teaching people about a game for so long and to a certain extent.
Now I know people don't like to draw comparisons between UNMC and the Police, but for the sake of this argument I will. The UNMC has heavily limited enlisting. The police has around ¬50% acceptance rate if I remember correctly to the academy statistics that were released. Compared to the UNMC who has more likely leaning to wards 5-10% enlisting rate (pure guess work, from the numbers we have compared to the number of applications we have, thats my guess), the calibre of people in the UNMC is obviously different when compared to the police. They are experienced and trained with arma mechanics, server rules and how things work. Compared to the police it is like comparing cupcake to a wedding cake. They each have potential to be great, but the wedding cake has so much more there. (Maybe not the best comparison). Its like using Tesco's/Lidl ingredients to make a cake, compared to fresh produce taken from a farmers market.
I have said this before and I will say it again, sort out the way you enlist and the caliber of people you accept. I have discussed this with certain members of police command before and it seems to resonate true with them as well, yet nothing has taken place to correct this. The police has close to 400 members, yet they seem to not be able to control them/train them adequately. Ask anyone from outside the police and start working with feedback.
