The Orlando Sentinel reported today that the Trayvon family lawyer, Benjamin Crump, has no intention at this time to sue the HOA. The importance of filing a lawsuit is paramount and is needed for justice.
The history of HOA governance has been the apathy of HOA members that allows boards to do as they please, and boards to allow HOA attorneys to, in reality, run the HOA along with the managers. HOAs have gotten away with no accountability under state protective laws, and by the obedience and acquiescence to board authority and pressures by passive members.
Suing the HOA would also serve as a wakeup call to this indifference to life and suffering that can have severe consequences, in addition to raising ethical and moral questions for our society. That good intentions still must be measured against courses of action that have foreseeable consequences of serious harm to others.
An explanation for this apathy and groupthink by HOA members can be found in HOAs where members band together in support of their boards, “right or wrong,” was offered in Why do people harm others in HOAs?, which is based on the Milgram and Stanford Prison Experiments. I’ve informed homeowners of the areas of potential liability by HOAs and the impact on the membership in What is an HOA’s duty of care liability to its members and to all others?

I saw reported that the family did intend to sue the HOA.
I agree that this is absolutely necessary.
