When someone confronted me about anything, I hit them in mid-sentence so it was never a problem. Nobody standing right there even knew what happened. All anyone saw was someone on the ground and the back of my head walking away. If they asked anyone, they'd say they had no idea what happened. CCTV isn't problem because if they ever did catch up to me, what was said is his word against mine. Socking someone immediately looks like an immediate threat was made. Drawn out arguments bring eyes, ears and witnesses of all kinds.
