Once there was a murderous drug-running dictator named Noriega who had pushed his luck too far and ended up ironically running to a Catholic mission sanctuary to escape justice.
Forces that had him on the run surrounded the Catholic mission but did not enter out of respect for the Catholic Church.
A siege was put in place but that’s not all. Loud blistering rock and roll was blasted into the sanctuary. so loud that it could be heard for miles. The forces that blasted the sounds away relaxed with ear coverings and headsets for communications.
The sound siege worked.
Negotiations between Catholic priests and force commanders resulted in turning Noriega over to justice.
The same can be done to the perpetrators of OFFENSIVE violence against the current political process. By ‘offensive’ means in reference to those who organize efforts to break up legal political rallies during the election season using illegal tactics and actions such as violence.
For the BLM crowd, just blast them with classical and/or CW music and they'll run away screaming like girls.
