I understand Grossman's concept of Sheep, Wolves and Sheepdogs, and that many of us would like to consider ourselves in the Sheepdog class. However, note that with real sheepdogs, you need to put them in with a herd of sheep to see what they've got -- are they sheepdogs or just dogs who don't have a clue about sheep.

Likewise, there are a lot of guys who have a lot of guns and make a good show on the gun range, but they have never been tested in the face of the targets shooting back. How many have seen the face of a victim surrounded by ice going hypothermic and certain to die if help doesn't arrive soon? Few of us. We can talk about preparedness, but we won't know if we can jump into that river until we see that face.

The videos make a good point regarding doing the right thing in the face of adversity. But you never know if you'll jump in until after you find yourself in the water.
