That "secret MIAC document" Vteckidd posted is pretty much common knowledge that anyone can find on youtube or wikipedia. Its a pretty common thing for law enforcement to pass out materials like this for training purposes. There are similar documents on "how to identify gang members" that discuss how some of the bigger gangs formed and who their suspected leaders are. Or "how to identify drug traffickers" etc etc

I mean when an officer sees a truck and its got RP and Stormfront stickers all over it, the plate number is "skn hed", and the 4 passengers are all wearing fatigues but none of them are active Military... it might be a good idea to call for backup before pulling them over for speeding.
