Pretending to be a victim can be a great way of disguising your own guilt, so this is a common trope on a mystery series.
In Film Noir, this became a stock trick for the Femme Fatale or The Vamp.
Often related to Guilt by Association Gag and Et Tu, Brute? Contrast Wounded Gazelle Warcry where it's not a trick.
Not to be mistaken with Deliberate Injury Gambit as well; that one is about someone getting themself hurt for real to achieve a goal.
An unidentified artillery private photographed by Charles Rees of Richmond shows this jacket (FIG 3), as does another Rees photograph of a pair of sergeants from Lynchburg, Virginia, Austin S. A photograph of Sergeant Thomas Crowder Owens of the 9th Virginia Infantry, who was killed at Gettysburg, also shows this pattern uniform (FIG 5). Other photographs are known from other units showing this same pattern.
When done on a large scale, it's often a False Flag Operation.Because these jackets were produced over a considerable period of time, and because they were made from materials available at different times, variations in the coat material and the number of buttons have been noted.The example shown above was worn by Private John Blair Royal of the 1st Company, Richmond Howitzers.It is rather difficult to determine the first pattern of jacket issued by the Richmond Depot. The distinctive point about the first pattern jacket, and the feature that distinguished it from the Type II, was that it was trimmed on the collar, shoulder straps and cuffs with either tape or piping.Apparently none survive; but based on photographic evidence, and later Richmond practice, it is believed that the first pattern jacket, herein designated the Richmond Depot Type I, was a jacket with a six piece body and two piece sleeves, with a nine button front, shoulder straps and probably belt loops. However, because all of these details must be either gleaned from photographs or inferred from later practice, there is still much that is open to discussion.
