The only reason the media found someone to leak a sealed police report is to target the Duggers, as they've been doing for years. They hate the fact they are Christians and do not shy away from their discussing their faith.
Now that they've offended the homosexual mafia, it was time to take them out, even if it meant breaking the law and hurting the girls all over again.
If the Duggers were big Obama supporters, advocating for homosexual "marriage," and constantly decrying "Christian bigotry," then this never would have been leaked, and if by some chance it had, they would have been given a pass.
Heck, in a few years with as fast as the slippery slope is going, such behavior probably won't be illegal.
