Can you remind me where the goalposts are?
Of which the data collectors had neither. Second hand and third hand reports are not observing something occurring or experiencing it occurring. That is someone else's recollection of the events.
If what you're trying to suggest is that any recollection of an event that originated as someone's observation or experience is empirical than there are no anecdotes. Every one of these stories either didn't happen or started as someone's experience.
Whilst I agree some reports are second hand, the majority of incident reports are completed by those involved in the incident; therefore first hand. But even the second hand statements from the Coast Guard are completed in accordance with PACE (Police And Criminal Evidence Act).
Here you go. Apologies for the day's delay - I had to take the pictures.
PICTURE 1 (BS BA 1)
1. Start with a bolt snap - choose whatever size you prefer. The one in the picture is a small one I had available, but I can manipulate this one without gloves.
2. Pick an O-ring. In the picture I have put a yoke valve O-ring (014) and a DIN regulator O-ring (112) in to illustrate options. Either will work (as will many others, I happen to have plenty of these around the shop).
3. Pick a cable tie. In the picture I have put a small, thin 4" cable tie, and a more commonly used 9" cable tie (which i use on regulator mouthpieces). Either will work.
PICTURE 2 (BS BA 2)
4. Wrap the O-ring around the base of the bolt snap.
5. Run the cable tie through the 'ends' of the O-ring.
PICTURE 3 (BS BA 3)
6. Attach the bolt snap to the regulator second stage hose, using the cable tie. (then tighten it down, and clip the end, to 'clean it up')
With the bolt snap clipped to a right shoulder D-ring on your harness, a sharp tug on the second stage will reliably break the O-ring, and free the hose (leaving the bolt snap still clipped to the D-ring). With the thinner 014 O-ring, less of a 'tug' is needed, than with the 112. But, either / both WILL break away quickly.
Hope this helps.

For clarity, where the data in the BSAC incident report comes from is published in the report. There is occasional overlap, which the report writers attempt to minimise by collating the reports from multiple sources into the one incident.

Explanation of sources quoted.
BSAC report - Report submitted by those BSAC members (witnesses) involved in the incident. May be multiple reports from multiple participants e.g. diver and buddy, surface cover, incident manager, etc. These are members first hand reports of their view of the incident. Not all members choose to submit reports. There is no legal requirement to submit a report. However, an incident report is required if the BSAC third party insurance are involved.
Coastguard - Her Majesty's Coastguard (HMCG) is a section of the Maritime and Coastguard Agency responsible, through the Secretary of State for Transport to Parliament, for the initiation and co-ordination of all maritime search and rescue (SAR) within the UK Maritime Search and Rescue Region.
Media - All forms of news reporting media, print, radio and television. This information is provide by a commercial media news collecting agency.
Other - Sources other than those specified. Including the British Hyperbaric Association, Coroners Courts, Police service, etc.
RNLI -
The Royal National Lifeboat Institution (RNLI) is the largest charity that saves lives at sea around the coasts of the United Kingdom, the Republic of Ireland, the Channel Islands and the Isle of Man, as well as on some inland waterways.
Volunteers: 40,000
Region served: United Kingdom; Republic of Ir...
Main organ: The Lifeboat
Legal status: Registered charity
Under other I should also mention
PADI - Europe, Middle East, and Africa
MOD - Ministry of Defence
RSPOA - Royal society for the the prevention of accidents.
SSAC - Scottish Sub Aqua Club
SAA - Sub Aqua Association
CFT - Coomharile Fo-Thuinn - Irish Underwater Council
BDSG - British Diving Safety Group
For those not familiar with the RNLI, I strongly suggest you google it. It is the principle organisation that is dispatched to rescues by the Coastguard. Those crewing the lifeboats, and providing lifeguard services are all volunteer members of the public who receive no reward or payment. They are available 24hours a 365 days of the year.
Despite their expertise and equipment, there are and have been tragedies. I don't know of any recorded case were they said they would not launch.

So, at least for 2018, more than half are from second and third hand sources (not considering that any of the bsac incident reports may also be).
Which again, doesn't mean they aren't valuable or useful data, but doesn't make them empirical by anyone's definition.
Perhaps a better approach to this conversation would be to say "if we wanted to prove X, what kind of data/tests would we need to provide adequate evidence to do so?"
