I'm surprised the Daily Telegraph printed this story...it's more the style of the Daily Hate. Whilst it's not on that any injured service personnel should have to put up with this, the story itself is based on hearsay. Not good.
If the "offender" had done it once and was warned about it, then I would think he could have been nicked a second time for threatening behaviour under the public order act.
Hey ho, I wasn't there and neither were the Daily Telegraph.
As an aside I totally agree that service personnel injured on active service should have their own medical facilities and not be in NHS wards.
