Just happened here in Austria. Police took 20 people into custody (13 have since been formally arrested) for luring people to fake dates where they beat them up.
The suspects said they hunted pedophiles, but at least in some of the cases they targeted young adults who expected to come to a date with 16-18 year olds.
They lump far more people into the same group. They attack anyone whom they think they can, even if they know that their accusations are BS.
