After years of on- and off-duty medical response in both urban and wilderness settings, I will say this:

1. The fear of litigation is vastly overblown.

2. Plenty of EMTs and paramedics give bad advice and are victims of severe cognitive bias. They only know their own experience, and they frequently misapply that to everyone else's situation. Crusty medics are some of the worst.

3. Remember that your loadout, and your litigation concerns, needs to take into account working on yourself and family/friends, not just strangers. This changes the equation.

4. Many of the comments at that LifeHacker site are ridiculous. See item #2 above.
