* GreaterScopeVillain: the lab tech Brady pays to frame Benson has already framed a dozen other people and his scheme will wreak havoc on the judicial system, which relies on DNA evidence.

* IdiotBall: Benson insists on doing an interview with IAD after she's been arrested instead of getting a lawyer when the rest of the squad is lampshading what a bad idea this is (as Benson already knows). Eventually she acknowledges this is a mistake and lawyers up.

* ArtisticLicenseBiology: While convenient for the plot, there are ''many'' reasons why saliva can't be mixed with a blood sample to change it to someone else. That isn't what occured. This is based on what a company was able to do which was take someone's dna that had been profiled either already in a dna database or from a sample of saliva or blood, then fabricate saliva or blood with that dna. Saliva from Benson wasn't mixed in with blood. Her saliva was used to make blood with her dna that was put on the knife. . https://www.technologyreview.com/2009/08/17/210960/how-dna-evidence-can-be-falsified/

* StatusQuoIsGod: The episode ends with the idea DNA is no longer a feasible form of evidence thanks to the [[HollywoodScience saliva-to-blood technique]]. It's never brought up again in the show and DNA comes back as a valid form of evidence. ArtisticLicenseBiology aside, it could be [[HandWave Hand Waved]] that a method was found to tell the difference. Once again whoever put this didn't do any googling. The same company also put out a test to verify if the dna sample was faked. https://www.technologyreview.com/2009/08/17/210960/how-dna-evidence-can-be-falsified/
"An Israeli company, called Nucleix, has shown that it’s possible to fake DNA evidence at a crime scene, a possibility that has been cited as a concern for those who make their genome sequence public. Nucleix, based in Tel Aviv, has also developed a test that can distinguish between real and fake DNA evidence, i.e. DNA that has been shed from a person, and synthesized DNA that has replicated from a small DNA sample or generated anew from an individual’s genome sequence."

Benson ends up the prime suspect when her DNA and business card is discovered at the scene of the sexually mutilated body of a member of a biker gang known for prostitution and contract killing. Further investigation leads to revelations about new developments in DNA technology that might prove troublesome for SVU detectives.

While in the park, a family stumbles upon the sexually mutilated body of a biker (Creator/EddieAbele) whose gang is known for prostitution and contract killing. To everyone's surprise, incriminating DNA evidence points to Detective Benson as the prime suspect. Munch and Fin investigate the murder, while Stabler fights to prove his partner's innocence. Benson is confronted by a criminal she arrested years earlier (Creator/PatrickHeusinger). Having endured years of sexual abuse in prison, he framed Benson with the help of a questionable doctor (Creator/JRobertSpencer).

* CastingGag: Benson is defended by recurring defense attorney Trevor Langdon. Offscreen, Mariska Haggerty and Peter Hermann are married.

* MyCard: Olivia was actually framed by Brady Harrison who killed Clyde Vandyne and left Olivia's card on the body... as well as her (fabricated) DNA on the knife.

* BeCarefulWhatYouSay: The detectives and ADAs often make mention of prison rape when interrogating suspects. This turns around and bites Liv in the ass in this episode when Brady Harrison, a man that she interrogated and was later convicted, was raped in prison: he believes Liv arranged for him to be raped, and in revenge, had her DNA fabricated when he gets out so he can frame her for murder.
