Either the guy was out of it, or reckless...
I can't see any other logical explanation, unless the AIB come up with something radical...?
Scuffers....in a clear concise unambiguous manner....lay out your case for the points you made in the quoted comment.
A) The Guy Was Out Of It!
B)The Guy Was Reckless!
As I am sure you do not have access to the information, evidence, lab testing, and forensic evidence the AAIB does.....I am quite interested in hearing how you arrived at those two Options for what happened that night.
Do tell us in detail what you base those two Options upon....be specific will you as very few of us that are following this investigation seem to have been able to garner such an interesting and definitive insight as you seem to have done.
Do educate us will you?
