Peggy Noonan wants an investigation into the IRS and its behavior over the last few years. She has ample justification for one:
We do not know who ordered the targeting of conservative groups and individuals, or why, or exactly when it began. We don’t know who executed the orders or directives. We do not know the full scope or extent of the scandal. We don’t know, for instance, how many applicants for tax-exempt status were abused.
