Your remark sounded gratuitously snarky and dismissive. You write "Spoken as a mom"--do you speak as the mother of a U.S. Marine? Do you know what the training of young Marines is like? Realistically, is there ANY way at all that you could know that these young men "didn't probably pay enough attention to their training to do their jobs correctly and carefully"? Unless you have some direct experience, as some Freepers upstream on this thread do, perhaps it would be best to refrain from saying "Oh, too bad" in that insultingly dismissive manner, with all associated self-righteous implications.
People are dead. Show some respect.
‘Scuze me -
I am sorry these young men died.
I admire them for joining the service
My heart breaks for them, for their families.
I know nothing about munitions or the details of this accident.
I am so sorry they died.
