History has shown, that public executions can have an effect on behaviour.
I say bring them back.
My preference is firing squad, although I can be convinced otherwise.
I recommend this for Schitt, Obama, Kankles and all the other traitors:
The Brutal Story Of William Wallace’s Execution That 'Braveheart' Wouldn't Show You Noelle Talmon
William Wallace was a Scottish knight active during the late 13th and early 14th century, and an instrumental figure during the Scottish wars for independence. Many people wonder what really happened to William Wallace, and how William Wallace actually died. In 1297, he defeated an English army and was subsequently named Guardian of Scotland. A few years later, in 1305, he was captured and sentenced to death by King Edward I of England for treason and other crimes.
The death of William Wallace was brutal. He was hanged, drawn, and quartered. William Wallace's execution was featured in the 1995 film Braveheart, which was directed by and starred Mel Gibson. What happened on film was very different from what happened in real life, however. The Braveheart inaccuracies include Wallace's death scene, which was severely toned down and did not portray the torture and pain that the real Wallace endured before crossing over into whatever it is that comes next.
Wallace Was Dragged Naked For Six Miles Through The London Streets
According to legend, Wallace's enemies took him from Westminster Hall, where he was tried and found guilty of treason - the punishment for which was drawing. He was forced to remove all of his clothing and tied to horses, which dragged him approximately six miles away to Smoothfield.
While the horses were pulling him, bystanders threw garbage, excrement, and other objects at Wallace as he made the journey to the gallows. They also hit him with sticks and whips. In the film, the crowd at the gallows pelted Gibson with rotten food and other objects, but he is wearing clothes and not covered in human excrement.
Then, He Was Hung - But Not To Death
After being dragged naked through the streets of London, Wallace was hanged. He was hanged as punishment for robbery and homicide. Dying in this traditional way wouldn't have been adequate punishment for Wallace's purported crimes in the eyes of the British monarchy, however.
Rather, being strung up from the gallows was just another step in an unbelievably drawn-out execution.
The Executioner 'Emasculated' Him And Burned His Intestines In Front Of His Face
Once Wallace was secured, his executioner sliced off both his penis and testicles (called "emasculation"). Then, the executioner removed his intestines (known as "disembowelment" or "evisceration") and burned them, making sure Wallace witnessed the act. He was disemboweled for sacrilege.
After The Disemboweling, His Heart Was Ripped From His Chest
The mark of a truly exceptional executioner was that they could not only pull the heart out of a criminal's chest, but they could also keep it beating the whole time. While there's no record of Wallace's hangman's success in terms of keeping his heart beating, Wallace did have his heart removed after his entrails and genitals.
The hangman then declared, "Behold the heart of a traitor," as he held it up for the crowd to see.
Then, He Was Beheaded
After Wallace was beheaded, he was quartered, which entails all four limbs being tied to separate horses, which then pull apart the body. Afterwards, Wallace's quartered remains were put on display around London as a warning. A piece each was hung at Berwick, St. Johnston, Stirling, and Newcastle-upon-Tyne.
In the film, a voiceover by Robert the Bruce describes how Wallace's body was torn into pieces and his head and limbs were displayed all over Britain as a warning to enemies of England. Wallace was quartered for "divers depredations."
Wallace's head was fixed atop a spike and put it on London Bridge so everyone could see it.
