The interesting thing about this is that almost exactly the same thing was done in Chemnitz, Germany, in 2018. A killing by a migrant led to several anti-migration protests. To stop this rhetoric taking hold, the establishment put on a concert, had it broadcast on a dozen different radio stations, and bussed in antifa from all over Germany to attend it to create a show of strength, vastly outnumbering the anti-migration protesters and distracting normies with "fun".
