Police in southern Sweden have a new tool for fighting sex crimes: a dog named Rapports Opus that is trained to detect the presence of sperm. According to English-language newspaper The Local, police in the town of Karlskrona arrested a 23-year-old man and charged him with rape after Rapports Opus was taken to a park where a woman was sexually assaulted. The dog found traces of semen and after being sent for analysis it was found to match the 23-year-old's DNA.

Oh, Christ. And I thought regular dogs always sniffed my ass.
