Fascist rulers crack down on artists because art gives people hope and often contains symbols and messages that are critical of people in power, which makes it a dangerous tool against absolute rule.
But sculptor Alfie Radley didn't turn 100,000 knives into the world's most dangerous sculpture to protest political policies in the UK, or give people hope for that matter, and the British authorities actually aided in its construction.
Alfie built the 26-foot-tall Knife Angel to raise awareness about the rising knife violence problem in the UK and honor the victims:
The angel’s founder, Alfie Radley, has spent two years designing and building the sculpture that features authorities donated knives that were actually utilized in violent crimes all over England and Wales, some of which even have the names of the victims engraved onto the blades. The rest arrived thanks to the aid of British Ironwork Centre in Shropshire, which initiated an amnesty program “Save a Life, Surrender Your Knife,” through which individuals can anonymously contribute their knives to the project.
