So does every location in the country need to have armed people around? There can be no "soft targets" anywhere?
There is a better way, other countries have figured it out already.
Yes, nobody does ever kill anyone in other countries.
We have individual murders, but our last big mass shooting was in the 90s. USA has one every day. Your comment seems to deliberately misinterpret the situation.
Who is “we”? This was a few days ago: https://en.m.wikipedia.org/wiki/Carcassonne_and_Trèbes_attac...
(Edit: nevermind, I guess you’re talking about Australia and not Europe)
People committing violence choose soft targets over hard ones when they can.
