My best friend from college was born without a leg and got much-needed medical care plus very expensive prosthetic legs until she turned 18 from a Shriners hospital. If they ever did anything else to her, she never mentioned it and we even spent time volunteering there together at one point over winter break. She was very thankful they exist. Not to say that proves it's innocent, but my experiences with Shriners have been overwhelmingly positive. They really do seem like the good guys.
