323 police officers from 13 countries will be working for the World Cup in Germany. Deployed partially in an effort to prevent hooliganism, they will patrol with German police officials. Some will be in plain clothes on German borders to stop troublemakers, others will work in uniform in German cities. The German interior minister said this level of cooperation would have been unthinkable in the past; it is a symbol of how Europe is growing ever closer together, he added. The British Transport Police said the foreign police hope to help stop misunderstandings between foreign fans and local police.”]
