This is going to grow worse as the rallies continue. The communists will learn and improve their tactics in successive rallies... UNLESS they are stopped.
Pre-rally preparation must improve so as to keep the blm/antifa communists well-separated from rally-goers.
If municipal authorities and local police won't do it, then perhaps local militiamen will step in to fill the void.
You're laughing. That won't work?
Then who else are you going to get to do the job...?
