owning weapons to protect oneself and one’s fellow human beings is absolutely justifiable, but the uncontrolled acquisition and loose carrying regulations in public spaces are definitely not.
This incident in France proved that strict regulations only affect law abiding citizens. Having one “side” disarmed might prevent escalation but it also strips them - but not the others - of the possibility to exercise their right to defend themselves.
I guess it helps that the left frame is filmed with a potato.
