From the BBC:
A ceremony has been held in Berlin to present more than 300 police officers from 13 European countries who will be working in Germany for the World Cup.
…
Britain has the largest contingent, with 82 officers, who will be in uniform and have powers of arrest.
I wonder if they also have powers to gun down speedy Brazilians who are judged a serious threat to Englishmen? If I were Ronaldinho, I’d want to know.
