Final answer:
The biggest challenge in prosecuting frotteurism is the difficulty of gathering evidence and the occurrence of the offense in crowded places, victims' delay or reluctance to report, and proving the perpetrator's intent.
Step-by-step explanation:
The biggest problem in prosecuting frotteurism is proving the intent and the occurrence of the act itself. Frotteurism is a sexual disorder characterized by someone rubbing up against a non-consenting person to achieve sexual arousal. The challenge in prosecution arises from the typically crowded environments where these acts occur, like subways or concerts, making it difficult to identify and collect evidence against the perpetrator. Furthermore, victims may not realize an offense has occurred immediately or may feel too embarrassed to report the incident, leading to a lower rate of conviction.
Historically, groups have faced challenges in the criminal justice system related to identity and human rights, as reflected in the previous harassment of the LGBTQ+ community, where discriminatory laws were used to justify arbitrary arrests and denial of civil rights. These historical examples reflect broader difficulties in criminal justice concerning the regulation of sexuality and privacy, which also pertain to the effective prosecution of sexual crimes like frotteurism.
