The idea of a civil suit is recurring in this thread, as it does in so many others relating to diving.
Before folks worry about a civil suit they should look at what Good Samaritan Laws actually say.
Definitions are in order as well; "duty to act" "standards of care" "acting within training" and in relation to this thread "freedom of the press"
Good Samaritan Acts basically exist to prevent the fear of lawsuit from stopping would be rescuers. he laws vary from state to state, in some states only trained people are covered, formal first aid training, or CPR etc. The common thread of these laws is consent, training, and stopping.
Duty to act/rescue only applies to professionals, police officers, firefighters and so on in he course of their duties, it is a general duty, not specific.
There are a couple of states that do place the duty upon regular people, though enforcement is seldom.
Standards of care relate to the duty of care; if one has a duty of care (generally professionals in a paying relationship), then the care must be reasonable in relation to the standards of the profession.
Acting within training is important for amateur rescuers, this is the component that will nullify any protections afforded by Good Samaritan type laws: do not do anything one is not trained and practiced to do. In California some well meaning rescuers pulled a person from their vehicle not heeding the victim's desire to be left alone. The would be rescuers claimed imminent danger from fire. They turned the victim into a paraplegic. They had two problems; they were not trained to extricate a victim in those circumstances, and did not have consent from a conscious victim.
Whatever freedoms the press has (which relates to government interference, not the ability to annoy/harass private citizens) does not apply to Joe Ghoul with a cell phone or handy cam.
Generally speaking most private citizens are not worth enough to launch a civil suit against.
Civil suits are launched on the "deep pockets" guideline. The entity with the deepest pockets gets sued.
Most people are not worth the time of a wrongful death or negligence suit.
And those with the resources to be worth a suit have already protected their resources.
