UK Guide: Dealing with Mentally Disturbed People
I'd like to share a little story about being on the London Underground, although if you know anything about British pop singers in the 1990s, you might find it more interesting.
Since the closure of most psychiatric hospitals in the UK in the 80s, many people with serious mental health problems who have not received treatment have started to live on the streets, creating a large number of safety problems. Imagine how much chaos a person can create by an aggressive, unrestrained person wandering around London for a day, and then multiply that by thousands.
Many of these people can switch between harmless and dangerous in an instant.
I have a feeling that this type of person may be more likely to target Chinese for a similar reason to why teenagers might target Chinese – because Chinese look "different" in appearance and therefore attract their attention and interest, which is unfortunately true.
