Men hunt for thieves in Venice. They make films for YouTube. They mark people with red paint. Or they use water. Many people watch these films. People often fight about this.
A man is Mervin Hunter. He hunts for thieves. They shout the word pick-pocket. That means thief in English. Now people fight with stones. Police stop the groups.
Simone Venturini is the mayor. He does not like the hunt. He calls it self-justice. The city wants a good image. The city gets 50 new police officers. Monica Poli warns people too.
