The only reservation I have about a dealer is that we are dealing with marijuana, not meth or coke (no one, including KC, indicates there were large quantities or meth, coke or heroin being used or purchased).
Marijuana is a drug that is now available medicinally in eleven states (IIRC) and is de-criminalized in several other states (the equivalent of a speeding ticket)...Unless you are dealing in large quantities, marijuana is not something that people typically keep super stealthy under cover. They just buy it from 'Mike' down the street and try to stay as discreet as possible. Further, recreational users typically do not go out of their way to protect their dealers, they just want their pot and will get it where they find it, no biggie. I have a cousin that just lights up in the middle of D.C. out in the open, and never once does he worry about whether his dealer will be in trouble over his stupidity.
Now, if we are talking about elevating this to the level of smuggler, big-time dealing, then it is quite different-guns are typically involved, of course code names are used, and a lot of profit is built in on all levels-meaning KC at least once or twice would have had a nice payday. Yet she had no money to speak of.
Weak argument to me-and I am not even taking into consideration all of the other evidence that counters a drug strategy-I think she was just a toker, and maybe even knew of larger dealers (the guy accross the street from TL), but I don't think she came anywhere close to the top of the tier. From what I understand, guys holding kilos of marijuana don't sell it off by the quarter-They sell it off by the QP or pound. Girlfriend was not known to be holding by any of her friends.
