Correction: Earlier today I had listed several outfits that you could probably kitbash together to get the look you want. However it took to long for me to add the comment and all the information was lost. The basic police uniform has not changed much, but the special units like swat and some other uniforms look more and more like military attire. I think this outfit has more of the older police uniform https://www.daz3d.com/inspector-uniform-for-genesis-8-males.

I used this outfit https://www.daz3d.com/uniforms-for-michael-6 to create this image - https://www.renderosity.com/gallery/items/3190241/policeman-on-duty. The character is just basic G8 male.  There is variation in the hats, and shoes, but the accessories are basically the same. If there is a particular outfit you have questions about if I have it, I will be happy to answer your questions. I have a lot, but do not want to post the list here because it is a bit long.
