There are many, many models that have the Cop keyword in the Batman Miniature Game, and very few are not part of the Law Forces faction. Since getting back into the Batman Miniature Game, and painting the Patterson Batman and Batman on Bike, I next decided to tackle ALL the Cop models. Wow, oh wow. When I'm done I will have 44 Cop models from all three editions of the game (metal, resin, newer thermoplastic).
Here are the 1st edition models, with the Cop keyword, that I finished years ago: Commissioner Gordon, four street cops, and three SWAT.
I will have quite a few models that will also have the Detective trait. Its very handy, with the trait, to manipulate suspects at a four inch range rather than having to be right next to them. It also suits the Law Forces faction.
Here are some more SWAT, and two Gordons (Back to Gotham and The Batman sculpts), that also have the Cop keyword. A note about SWAT models is that they have the Elite trait, which means you can only take one of them in your crew. The caveat to that is if you have a model with the Boss: SWAT trait, in which case you can take as many as you want. When I finish these models, five will have that trait (2 Gordons, Aaron Cash, Lt Brandon, and Commissioner Loeb).
Then there are the rest of the Cop models! They are from the Nolan films (3), Back to Gotham starter set (4 plus one detective shown earlier), The Batman starter set (6 including the Gordon model shown earlier and yes the horse mounted cop is in that set), Gotham Central Cops (4 total including the two shown earlier), and Commissioner Loeb from the first edition (Commissioner Loeb and Gotham Police blister).
The models are in the final stages, after I've used the army painter method of using one colour on each model than starting at the first model with the next colour. I will be posting them as I put the finishing touches on them starting with the oldest models to the newest in each set they came out in.
