They want good suggestions as to how to prevent the problem of covering up abuse and disempowering the "authoritative bodies" from exerting overt influence in this matter.
This issue is broader than abuse and goes to the core of JW doctrine in many ways. My first suggestion will be for them to lose tax exempt status.
Mandatory back ground checks of members and child safety requirements/processes need to be put in place.
Enacting laws that abolish Botchtower's harmful doctrines is needed. This should include eliminating:
1) Coercing people into not taking lifesaving medical treatments
2) Encouraging people not to take higher learning/education
3) Shunning
4) Mandatory Field Service and browbeating people who can't do this
