I don't think it's right to blame it on the marines. It's not their fault. Not the soldiers, nor the airmen, or seamen that are injured or killed for no reason.
Firefighters volunteer to fight fires, that's right. What you're saying is that when a firefighter is hurt or killed fighting a fire, it's wrong to hold the arsonist responsible. I say the arsonist should burn in hell. Don't blame the firefighter for doing his job.
