The enhancement is doing so "in order to obstruct the administration of justice" -- I don't think that any of the actual dangerous actions were done to obstruct.
> Substantial interference with administration of justice
That's defined as a "premature or improper termination of a felony investigation; an indictment, verdict, or any judicial determination based upon perjury, false testimony, or other false evidence; or the unnecessary expenditure of substantial governmental or court resources."
I think the first two don't fit the factual picture that we're aware of; the last _could_ but I think it unlikely that there was that much conduct that was beyond the obstruction charge that caused this.
> Extensive in scope, planning, or preparation
Possibly - the SG don't go into much detail about what they mean by this; however, I would be surprised if this enhancement applied (but less so than the other two).
