Most didn't begin to transfer docs off site until after the meltdown which is even more disturbing. I have to wonder if the public would stand for this if they had a clue it was happening.
The lost docs weren't due to shipping offsite. All docs are scanned in the US and then sent electronically to be reviewed. $5 an hr in India v $15 in the US saves big bucks
Lost docs from the meltdown was primarily the multiple transfers and chain of custody.
