I'm a bit dismayed that the cops have been in the media pegging her for a serial killer, with their 'sting operation' where they found her with a full syringe.. the comments to the media pretty much indicated that they are taking this as proof of intent to murder.
I think they're being a tad overzealous there. Yep, it looks damning, if you have a preconceived belief she's a serial killer. But looking at it another way, a seriously addicted person hired for several hours of sex work MIGHT not want to cook their smack on a spoon in front of a client, and be addicted enough to want a hit handy in case the booking goes overtime.
Anyway, that all ought to be kept out of the media, if they want any hope of a fair trial for this woman. But maybe they don't.
