The .44 magnum gun - and Dirty Harry -
called out by the Rolling Stones.
https://en.wikipedia.org/wiki/Doo_Doo_Doo_Doo_Doo_(Heartbreaker)Written by Mick Jagger and Keith Richards, the song's lyrics relate two stories: one is a story of New York City police shooting a boy "right through the heart" because they mistook him for someone else, and the second of a ten-year-old girl who dies in an alley of a drug overdose. Neither of these events are known to be factual.
In April 1973 a ten-year-old boy named Clifford Glover was with his father when plainclothes police stopped them at gunpoint in Queens, in New York City, supposedly having mistaken the two for suspects in an armed robbery (the robbers were described as being about one foot taller than the boy). The boy and his father ran, fearing that they were about to be victims of a robbery. The police chased them and one officer shot the 10-year-old boy in the back, killing him. The bullet entered Glover's lower back and emerged at the top of his chest (i.e., went through his heart). The case resulted in riots and a murder indictment against the officer, who was later acquitted in a jury trial.[1]
After telling the story of the police shooting the wrong person, Jagger sings,
You heartbreaker, with your .44, I want to tear your world apart.
The .44 magnum cartridge had recently been made famous by the 1971 film Dirty Harry, in which Harry Callahan uses "the most powerful handgun in the world" to cleanse the streets of crime. The lyrics complement the music, which Rolling Stone magazine described as "urban R&B" for its funk influence and prominent clavinet part (played by Billy Preston).[2]
