“called for Americans to withhold judgment until they heard both sides of the story.”
Side one of the story: Bergdahl’s platoon members report he deserted.
Side Two of the story” The Army says Bergdahl walked off/deserted more than once.
Conclusion: Bergdahl deserted.
The “other side of the story” is Bergdahl’s defense.
It’s not likely to be very convincing, but it is, IMO, always wise to listen to the other side before making a judgment.
