Well they did get caught.
Check it out:

Perhaps the biggest fiction of this past year was that the IRS’s targeting of conservative groups has been confronted, addressed and fixed. The opposite is true. The White House has used the scandal as an excuse to expand and formalize the abuse.

About a month after the IRS inspector general released his bombshell report about IRS targeting of conservative groups last May, Acting IRS Commissioner Danny Werfel unveiled a “plan of action” for correcting the mess. One highlight was that targeted groups would be offered a new optional “expedited” process for getting 501(c)(4) status.

The deal, which received little public attention, boiled down to this: We’ll do our job, the IRS said, if you give up your rights. Those taking part in the “expedited” process had to agree to limit to 40% the amount of spending and time (calculated by employee and volunteers hours) they spend on political activity. Current 501(c)(4) rules allow political spending up to 49%, and have no “time” component. The clear point of the “deal” was to use the lure of 501(c)(4) approval to significantly reduce the political activity of targeted conservative groups going forward.
