In fact, someone already had the double-dipping up on the internet:
The episode begins with a murder victim who has been sexually assaulted, but turns into a case where the Special Victims Unit chases down a guy who is knowingly infecting women with HIV. It’s a story already done by the Law & Order "mothership" years ago in the episode “Carrier, ” which included one of the more memorable Jack McCoy quotes: "Hey no baby, I don't use rubbers, it's better bareback." (I still laugh at that line when I see that episode, it’s something about hearing Sam Waterston deliver it.)
The 2010 show had some internet window dressing: the website for AQ – Anonymous Quickie, “log on, hook up, get off”, but the legal issue was unchanged from the last visit by L & O. While Olivia cited some court precedent, she could perhaps have cited the earlier Law & Order.
