Wow....just wow. So I take it you're trying to imply that marines are just uneducated hicks by your excellent use of the English language there.
First of all those terrorists could have very well surrendered the day before and made it clear to the first group of marines that they surrenedered. That group of marines was most likely not equipped to take prisoners so they left them in the mosque for someone else to pick up.
Second of all......YES that is EXACTLY what they do. Do you really think it is so far fetched that as soon as the original marines were out of the area they would have thought twice about re-arming themselves or possibly stapping an IED device on so they could suicide bomb. Oh of course not.....they're too honorable for that.
As for your insinuation about the trailor park....very classy. I just love pure and utter ignorance right out for everyone to see.
