Pretty sure (however not totally confident) that this one is mod:/specs/ and you're looking for portraits.xml in this one. This one has to point to the same name as used in the lang folder, and also has to be the same name in the unit folder, or it'll return that white box error. I think, however I'm not positive..
No because it's fictional. Also, it's not from Los Angeles.
This mod only covers real agencies, and the vehicles they used, and re-created to the best of our ability.
I'll probably make the Striped Tomato for another project at another time in the future.
