He did it all in the name of fighting blasphemy.
Qadri's supportersÂ consider himÂ a hero for defending Islam. His home is now a shrine, andÂ he was beenÂ showered withÂ rose petals by lawyers when he appeared in court, according to the Washington Post.
Monday, the 26-year-old policeman pleaded guilty in a Pakistani court to murdering Salman Taseer, Punjabâ€™s provincial governor.
Qadri said he killed Taseer because of the governorâ€™s opposition to Pakistanâ€™s blasphemy law, which dictates that criticism of the Prophet Mohammed is a capital crime. Thousands of people have demonstrated in support of the law and at the rallies,Â banners supporting Qadri have been present.
"Mumtaz Qadri sacrificed himself to protect the sanctity of our prophet, and every one of us here is ready to do the same thing," a seminary student and protester told the Washington Post.
The assassination, which has sparked outrage from some, also has "quickly united and emboldened a broad spectrum of Islamic groups," according to the Washington Post.
