YesI remember the shot girl reference. I beleive AL said it. I seem to remember that he hired her for that position and to drum up business for him at Fusions. SOunds like he was a "john" as well. JMO
The "manager of shot girl" thing is pretty inocuous. She did this only during the time she knew Tone, so not that long at all. If you've ever been to a club, there are all kinds of hot girls skimpily dressed promoting all kinds of things. Some of them are hired by the club/bar to serve shots or just to pump up the crowd and be provocative and good-looking (this lures in new patrons when people go home talking about how hot the women were, etc).
It's not clear if the shot girls in this case sold shots to the crowd or danced around. In any case, IIRC, this is a sushi restaurant that becomes a club only on the weekends--not exactly a hotbed for any of the things people are trying to pin on it (drug dealing, gang activity, escort, prostitution, etc). IMO, this is being blown out of proportion and everyone is looking for something more scandalous and exciting and criminal than it probably was (the club, I mean, and activities there).
I also do not think Casey was hooking or escorting in any formal way (who knows if it happened occasionally, but I still doubt that). I agree with others who said she would not need to shop at Target if she was -- remember, she paid no rent or bills or food -- all the $$ she would have made was basically disposable. She constantly complained about her mother controlling her -- if she had half a chance to make decent $$ as an escort and she wanted to, she would have done so. But she would have moved out or at least bought conspicuous things for herself, none of which she had (unless we don't know about some very nice clothes or jewelry or lifestyle of expensive restaurants and clubs). I have no idea what she was doing when she was supposed to be at work -- at home, with friends, at the park with Caylee, at Starbuck's, somewhere with free wifi, texting and talking to people, etc.
