You keep saying this. But is irrelevant.
I also never saw people getting murdered in South Africa and I do not know anyone that was murdered.
Yet there is 64 murders a day in South Africa.
October 28 there was a mass stabbing in the UK.
1 November there was a mass stabbing in the UK.
I'm sure you do not know any of these people that were stabbed. It did happen though.
YT and other social media has DAILY videos of people running around with knives in the UK, stabbing or threatening others. The fact that it it is, according to you, "mostly gang related" is also quite irrelevant.
And yes, guns is not the answer. The problem lies in the current state of social decay the world is experiencing as well as major culture clashes, based on unchecked migration.
