Careful here. Keep time frame clear. The "crash" and / or "crashes" were in 2011. The "recovery effort" is more recent.
Two things: The improbability of multiple hard drive crashes involving multiple persons of interest.
And
How "convenient" that they did NOT even attempt to restore lost data from the tape backups when they had it.
We are getting into some astronomical numbers as far a probability now.
The rep from KY mentioned probability, but what he did not take into account is how old Lerner’s hard drive was when it failed. It most likely did not fail 11 days after it was installed. The IRS has no interest whatsoever in producing anything that would tie them to the White House. Internal efforts toward that end are a joke. Way past time for a special prosecutor.
