A video of Moroccan youths insulting a rabbi on a street in Amsterdam has prompted the Dutch justice minister to say he might consider using undercover police wearing yarmulkes – called "decoy Jews" by the press – to combat anti-Semitism.
Ernst Hirsch Ballin says similar techniques are sometimes used to lure hard-to-catch criminals, like rapists, and could have some use in combating crimes against homosexuals and Jews.
Recent press reports have claimed anti-Semitism is increasing in the Netherlands due to friction with the country's Muslim minority.
Amsterdam's acting mayor, Lodewijk Asscher, says he, too, he would consider the idea. His spokeswoman, Tessel Schouten, said Friday the city doesn't yet have specific plans to use the technique.
