Same with child molesters. I've never had the local LE follow through on anything I've reported over the last 20 years. Even doing the footwork for them, everything goes into file 13 so this story isn't surprising.
I am beyond cynical when it comes to LE and their use of their budgets. Want to bet if the daughter, wife, sister or mother of a LEO is raped that their kit is processed? What sickens me is what the rape victim consents to for the kit in order to catch the perp. They are photographed, every bruise/cut is noted, an internal exam/swabs by a doctor, their hair is combed through (all places), their fingernails scrapped and they go over every detail over and over. When I was in college, I worked security for a hospital and sometimes it required me to be a female witness in the room. Many times, the rape victim just wanted to go home, shower and try to get on with their lives. What pushed many of these women to consent was the statement, “If we can catch your rapist, no other girl/woman will have to be raped by him.” Many of the victims endured the kit in order to prevent another person from being attacked.
