In response to a wave of killings in 1974, Manley oversaw the passage of the Gun Court Act and the Suppression of Crime Act, giving the police and the army new powers to seal off and disarm high-violence neighborhoods. The Gun Court imposed a mandatory sentence of indefinite imprisonment with hard labour for all firearms offences, and ordinarily tried cases "in camera", without a jury. Manley declared that "There is no place in this society for the gun, now or ever."
