"The Body Snatchers" by Jack Finney (1954) takes up a similar premise of extraterrestrials taking over the bodies of humans. Also in the plot of the 1956 "What Mad Universe" by Fredric Brown - as in that of "Puppet Masters" - police and vigilantes ruthlessly shoot down anyone suspected of being controlled by the book's invaders from space.
