I didn't know about this particular incident.
When I was living in London, this kind of thing was constant. I'm sure it happens all over the country.
It just isn't the sort of thing that would make national news. It happens too often.
I don't think anyone reported on that Southend machete incident last year. Usually I find this kind of stuff out from Twitter but these days I don't bother to click on anything happening because I try and stay in my local area - and it would be on the WhatsApp group quick enough if anything happened here.
When I left my London neighbourhood, the following week I had a message from a neighbour saying "I've just walked past another police tape/tent yhing due to a stabbing and I can't even be bothered to find out what happened. Does this make me a bad person" and I said "no." so many parts of the country are just used to it now.
McDonald's gets targeted, I think. I know two people who had to stop working there because it was just ridiculous.
