Its a fair point that they are repeat offenders insofar as public disruption is concerned.
Nevertheless, there are a couple of problems with your analogy.
1. PR, by their court statements, have important political, theological and cultural points to make. Teenage hoodlums do not.
2. Putin and his gangster government are the ones terrorizing the neighborhood.
I don’t know if Putin is really that bad or not but from these videos Russian government looks like a pretty peaceful bunch.
No batons, no kicks and punches for these “protestors”.
Two year term is a joke as well if you’ll listen them talking on Stalinism comeback.
