I say this as a joke towards the UK, but those guys go through hell. When Maria died I was put in a cell for a while before being questioned, and all other 6 or 7 guys where black dudes (proper dark black, from central Africa) having been caught trying to jump the border. I was living a nightmare, but even so managed to see the shambles they were in, most destitute people I have ever met.
And even then, not knowing anything about me and half wearing ripped clothing in winter, a couple of them tried to comfort and support me.
