exist, but that crimes should instead be treated as civil torts. Murray Rothbard writes, "In a libertarian world, there would be no crimes against an ill-defined 'society,' and therefore no such person as a 'district attorney' who decides on a charge and then presses those charges against an alleged criminal." Private prosecution is sometimes regarded with suspicion as a potential avenue for vexatious or malicious prosecution. Okagbue writes that the most useful control against such abuses is the power of the court to refuse to allow the case to proceed where it is of the opinion that there is not enough evidence to support the charge. The cost of private prosecution, including potential civil liability for malicious prosecution, can also deter frivolous prosecutions. Notable private prosecution attempts Oscar Wilde initiated an unsuccessful private prosecution for libel against the Marquess of Queensberry when the latter publicly accused Wilde of sodomy, which was then a crime. This was unsuccessful, and Wilde himself ended up facing charges brought by the DPP (following petition by Queensberry’s lawyer) and was ultimately convicted of gross indecency, with a punishment of two years at hard labor.

This trial was made into a play Pursuing Justice – Sex workers take their rapist to court, which was performed in 2015 to sell-out audiences. The family of Stephen Lawrence brought charges against the five men they alleged had killed him (1996). The private prosecution was unsuccessful; one suspect's acquittal in the criminal trial was quashed in 2011, with a subsequent trial resulting in his and another suspect's conviction in 2012. Following the 2014 police killing of Tamir Rice in Ohio, activists attempted to invoke the law to charge the officers involved. Although a judge agreed that there was probable cause for charges, he could only send the case back to the prosecutor due to the 2006 amendment to state law that bars judges from
