NDD,
I was always taught to clamp and ligate. When I became a civvie and had to go through a civvie refresher course, I yelled "clamp and ligate" to annoy my instructor. Civvies are not taught this.
Now. PHTLS and ATLS are just getting on board with the whole "tourniquet first" idea. Again in my refresher (5years ago) I stated for a serious bleed I would either 1)clamp and ligate or 2) tourniquet. This was not looked upon favorablly. Now civvies are moving towards "tourniquet first" due to ongoing battlefield use.
I don't think civvies will ever move to clamp and ligate due to liabilty, but I may possibly still carry my hemostats. Old habits and all.
