>Yes. But not just and not mainly from your government: you are way more likely to get killed by criminals and/or terrorists then by law enforcement officers.

That's not true globally; in the 20th century governments in Russia, Germany, China and Cambodia collectively killed over a hundred million of their own people.

>it makes them vulnerables to criminals and terrorists too. Which, so far in the western world, is definitely a much bigger threat.

Germany is the western world. Many of six million Jews would probably still be around if they'd been well-armed.
