No Such Thing As An 'Ex-Marine'?

Maybe they need to make an exception.

“It’s much worse than was reported in Time magazine,” Murtha, a Democrat, former Marine colonel and Vietnam war veteran, told reporters on Capitol Hill.
“There was no firefight. There was no [bomb] that killed those innocent people,” Murtha explained, adding there were “about twice as many” Iraqis killed than Time had reported.

Was he there? He just magically 'knows' more than Time learned in 10 weeks of investigation? Since he goes on TV and lies about the Commandant, his credibility is at zero with me.
