It's true the local body will decide, based on the "notariety" of a particular case, whether or not the KHall can be used. As to a funeral at a Funeral Home, that generally is left up to the individual elder, though some hard-nosed congregations might like to have some say or all the say.
In the past I have done funerals for some who others might not have, suicides, etc. However I believe funerals are for the living. Caring for people is our real assignment, I think, from Jehovah. Non-JW, JW, fading JW. All have the need for kindness and fellow-feeling. Something the WTBS is sorely missing these days.
