London has gotten worse, do you think this is debatable today? Plus I do not think that the "I feel safe" has much merit. It has some, but not that much. What if I told you I did not feel safe in London? You felt safe in some area, I did not feel safe in some other. I do not think this conversation would be fruitful if we focused on this alone.

Check the statistics[1] with regarding to robbing, knife crimes, homelessness, and so on. Perhaps that is a better starting point?

I have been told by many locals to not wear an expensive watch around designer stores, or touristic hotspots because robbery happens on a daily basis, it depends on the time of the day and which day it is, of course.

I have watched many YouTubers visiting London as well and they tell quite the story, too.
