NO!
The fact is that there is no liability NOW. If there is no liability now for damage or even deaths that might result because a member acts upon what has been taught, there certainly would not be any liability if the Society dropped the blood ban entirely. Courts do not punish defendants for taking remedial measures.
This seems to be a very popular fallacy among the anti-JW and reformer communities. The Society is not scared of lawsuits if it drops the blood ban and is not "maintaining or slowly sliding towards accepatance" because it wants to avoid such law suits.
The Society is and has been slowly sliding towards acceptance of blood (and I believe that it must and that it eventually will drop the blood ban) but it isn't doing this out of fear of litigation.
It is sliding towards acceptance of blood/removing the ban on blood due to a host of other factors: 1) the younger generation of Witnesses no longer buy the old argument/scriptural rationale; 2) once they allowed the first blood fraction it made possible the insertion of the thin edge of the wedge; 3) Even the leadership is recognizing that if it wants to hold onto members and attract new ones, it needs to shed "harmful" beliefs and practices, especially ones so sketchy; 4) lack of solid "champions of the doctrine" at the highest level. The Blood Ban was pretty much a creation of Fred Franz and as more of the old-timers die off, few of the "younger" Governing Body and non-anointed Nethinim are willing to go to bat for this kooky bibilical understanding; 5) the future expansion of the Organization is in other non-Western lands (Eastern Europe, China) where the Government Authorities have been hostile to the Witnesses, in some part due to beliefs such as this one, the Society needs to grease the wheels in order to enter those lands and so it will drop the Blood Ban (as it has done with the Alternative Military Service, and even indicated with the Bulgarian blood situation); and there are probably a few other reasons that I left out.
But just to reiterate, the Society is not afraid of either litigation or even of monetary judgements. It has the lawyer-power and deep pockets to withstand both. There are only two things that strike FEAR into the hearts of the Society and the "powers that be" 1) becoming irrelevant and 2) not being in "control"
