As usual Kit does a crappy job of explaining things. The media sensalionist fruit is going after "Lions and Tigers and TRAINING FAILURES! OH MY!!!"
He doesn't explain that a check failure is much different than say, getting a failing grade in school. The FAA chases after DPEs that have too high of a pass rate. They chase after APDs for the same as well. Failures exists because the FAA mandates it. It has very different meaning to the general public because the can only liken it to school failures.
