The perception is that the UK is now a very dangerous place. It has been before but now it's worst. 20 years ago I went to visit some friend and I heard stories of bullies not even scared of adults and families where both parents would go binge drinking leaving the kids alone.I was there 6 years ago. Well I could have been in India.
The police at the border is horrible. The like to intimidate people. Compare to the USA it's a scary place.
