This only serves to highlight the silliness of providing PreCheck automatically to members of the military. The odds of any individual committing a terrorist attack are vanishingly small (hence why PreCheck should be the standard for everybody), but there's ZERO evidence that the military are LESS likely to commit these attacks. In fact, active duty military are statistically more likely to commit a terrorist attack than the population at large. Two of the three largest (in terms of fatalities) terrorist attacks in the US in the last twenty years were committed by active duty or military veterans.
Again, I'm not saying that members of the military are somehow dangerous, but rather that there is zero justification for treating them as somehow LESS dangerous.
