The UNSC flags make pretty good police or security crests, and aside from anything that actually says "Police", I think they look pretty good.
I added a spare M2 .50 calibre machine gun to the top from a 15mm WW2 Command Decision Sherman M4A1, and it's interesting to see this alongside the weapons from other manufacturers. The "Ma Deuce", as the M2 was known by GI's, fires a shell bigger than my finger and is definitely a vehicle or tripod mounted heavy support weapon, but the one shown below is smaller than the assault rifles some of my 15mm figures carry!
I also noticed some white flecks on the windscreen after I varnished it. I think these are actually accumulations of matt varnish on tiny pieces of fluff that got stuck to my satin basecoat. I'm going to remove them and gloss the windows.
here's some pictures with figures for scale.
I'm pretty pleased with the outcome. I have two more to do, and the conversions and paintjobs are nice and quick to do, so I should be able to have a nice little fleet of them soon. Along with the two Dodge-Tata Zebu Patrol Cars and the GZG Fan Van I picked up at Salute, I'll have a nice little motor pool for my Colonial Police.
