Tasers are used in the US and UK I know. And tasers are torture, esp. when used for pain compliance. Pain is very effective? Oh, thank you captain obvious. So is burning heretics and chopping off limbs.
Tasers are used in the UK to subdue violent criminals, it causes them a lot less pain than being shot. As fa as I know, we do not throw them in the bonfire of chop their limbs off. Tasers would certainly be welcome in other parts of the world, where the punishment for theft is getting your hands chopped off and for rape getting other things chopped off.
I'll just say this. People sometimes say the Supreme Court's opinions are never popular. But I tell people they uphold our rights and should be above politics. Their opinions should never be popular. Popular with either end of the political spectrum. And a police officer's job should never be easy. We'll be living in a police state when either of those things are true.
Compared to the US, a police officers job is far more easy in the UK, because they support the law abiding citizens. The also do not carry guns. Guns are also unpopular among criminals, because carrying a gun carries up to 14 years behind bars, even if it is not loaded. Criminals get stopped by police regularly, so they don't risk it.
