Cops are just one of many examples. Here are some other ways of legally killing people:
- joining the army
- becoming a doctor and systemically neglect women and poc
- fatally injuring someone in self defense
- getting someone pregant in places with abortion bans
Notice that I said killing, not 'murdering'. So long as it's either not deliberate or acceptable by law, you can legally get people killed.
Taiwan is a country.
Edit: I love how people who never stepped foot in Taiwan before or have spoken to any Taiwanese person feel entitled to have an opinion about this.
