Obama clearly used the IRS to target his political enemies, and there's a lot of anecdotal evidence to suggest he did the same with our intelligence agencies. This young man may have the proof needed to prove that fact... which will expose very high crimes.
A leader who would use the power of the IRS to harass his political opponents like Obama has done has shown he will use whatever he can get his hands on to harass and persecute his political enemies, real and perceived. And now we know they have their hands on everything. That in a society with so many laws it's been reliably estimated that the average American commits three felonies a day. This isn't going to end well.
