You see the police normally do this thing called investigation. I know here in the US the police have forgotten what that word even means, as they just react, often emotionally, jumping wildly to conclusions based on zero evidence.

You see not every police dept in the world has removed all investigation from the responsibility of their police forces..

There will be a well proportioned response, but it won’t be an actual SWAT team. There’s typically one such team per five to ten million people and they won’t move for a joke call.

But more importantly, with an order of magnitude rarer killings, there is much less of a “we’re at war with the bad guys” culture. In some countries discharging a weapon brings automatic suspension for the investigation, even if nobody gets hurt. Cops simply don’t tend get trigger happy in this environment.

The comment didn’t say it was only a single officer or that they were unarmed.

That makes a huge difference, thank you.

In other parts, citizens generally don't have guns, so the idea of an "armed individual" by itself is already hard to believe.

Guns are in many countries all over the world.

Yes they are, and they are mostly in the USA with 1.2 civilian firearms per civilian.

Yes, but almost 50% of all the civilian guns are in the US.
