I would imagine it is because they know the ID of the attackers (probably from CCTV) and do not want to give them time to 'do a runner' before they arrest them.
If you look at reports from Germany, they do report that attackers are migrants/refugees/Afghans. Unfortunately there have been many crimes.
So I don’t think that the charge that the aithorities are covering up is true, because similar attackers are identified.
Wikipedia says, "Hookah lounges are mostly found in college towns and urban areas and are regarded by some as a novel and chic way to socialize and embrace multiculturalism."
Well, she tried so-called, 'multiculturalism' and that's what she got!
Is there a lesson to be learnt here?
Yesterday there was a thread on FGM: C4 program about the Somali community in Bristol sending their seven year old daughters off to be "cut".
Now I would have thought that the only issue worth being debated was how to stop the FGM. But not how all posers saw it.
The Germans do not as a rule conceal attackers’ identities. In the case of the British Student victim, information has not yet been divulged, but that is probably for some legal reason, like the suspects have not yet been charged, or is still under investigation.
