Of course for examples of British soldiers shooting civilians at checkpoints and in other circumstances, there's no need to go back to the 18th century, or across the Atlantic, as I know ard macha wouldn't deny.

There has evidently been a deliberate decision by the authorities not to collate statistics about killings at checkpoints in Iraq. However from the occasional news stories that make it through, when there is a specially dramatic or horrifying incident, it is pretty clear that there have been an awful lot of these killings. And the fact that no statistics are kept seems to imply that there can have been no serious attempt to investigate what went wrong in these cases.

I find the implication in a few posts that, if there had been a failure to inform the US authorities, this would mean that there could be no blame in shooting up the vehicle a bit bizarre.
