Re: A gun is involved in every single mass shooting.
Australia had a mass shooting.
They then banned guns.
There hasn't been a mass shooting since.
The UK had a mass shooting
We severely restricted and banned gun ownership.
Gun shootings massively decreased.

Only the US feels the need to try and keep dangerous weapons in the hands of people as some kind of legal thing because obviously nothing has changed in the last 200 years. Only the US feels the need to have militias. (WTF does a country that powerful need for unregulated militias anyway)
Everywhere else at least rethinks things when bad happens, and accepts that some things have to change.
