I don't read tweets unless they're posted here, but this reminds me of something..Unfortunately I read many tweets from British women denouncing concerned or angry British men as racist and sexist for implying that imported populations were racially targeting women they think to be "our women".
From what I recall, a livid father of one of the victims was arrested (i.e. his civil rights were suspended) by the same police force which colluded to cover up the grooming for 20 years.
I was on a commuter train in Germany once and in the corner window seat of the four seat section on the other side of the isle from me sat a young German girl. At one of the stops a group of Syrian type characters got on with the whole jihad beards and everything and sat around her and were jabbering away loudly in Arabic. Closer to the 2015 invasion you would more often see these groups around and have the suspicion they were in an Isis training camp just a few weeks earlier. There was even a Twitter account (I used to follow it back then) which tried to photo match arrivals at European borders and airports with Jihadist photos from the middle east. She looked very scared and started giving me nervous looks as if I was somehow going to do something if that group started something. Anyway afaik nothing came of it but in these situations I try to just stay relaxed and sometimes pretend it's my stop and change carriages. At any rate, be quietly ready to rush for whatever exit there is. How many times you read about those random knifings..
