The caption read:
" An elderly Iraqi woman shows two bullets which she says hit her house [emphasis added] following an early coalition forces raid in the predominantly Shiite Baghdad suburb of Sadr City."
Unless they threw them at her, the setup and/or caption is a fraud. Personally, I'd allow someone to fling unfired .223 cartridges at me all day long. Preferably in 20 round boxes or 500 round cases.
