Yes there are a few cops but if u know the street scene u can tell who they are. Remember the street trade are the very poor largely and sometimes druggies. If the skin looks too pretty or the clothes look too clean or they smell really fresh or the language is too direct or too educated.... It is not street trade. I can't quite explain how u tell the difference but given what I just said you will be able to spot them right away. You can see the cops because they don't quite fit in. Plus if are really nervous, find one street trade u know is obviously street trade who you don't necessarily like and give him $10 for no reason and ask him to point out the cops to u and he will. They all know. And you can also have a permanent spotter. Ask "hey take this and buy yourself a sandwich. Wanna ask u something. Any trouble for me on the street today? Anybody I need to be careful of" he will tell u...
