Hi Brett
Mileage varies from country to country, but I archive AND backup the archive of ALL my electronic communications, plus switch on the date and time stamp on ALL pictures taken.
I've found it to be a bit like being in a court case where I'm facing an actively hostile prosecutor.
So, without plugging in to confrontation, I give them no wiggle room whatsoever. I think this is what they mean by High Quality documentation.
Bearing in mind that people $mugglers will get up to every trick in the book - see my other post on fingerprint transplants- I can understand the need for vigilance.
But being treated as guilty until you can prove your innocence runs counter to our much vaunted democratic traditions
