There is no doubt about it, they've admitted the inappropriate conduct.
As it relates to profiling, do you have any information to show that conservative non-profit groups are more likely to run afoul of non-profit regulations? Even if that were the case, the IRS is not charged with preventive screening of non-profits to prevent future issues, they are charged with collecting taxes. Your comparison doesn't hold water.
I don't get it, why do you and some others in the thread see the need to defend this action? It was clearly inappropriate, regardless of what groups were targeted.
