HBP: Swing or no swing?

But that HAS to be a swing if it can hit a fair ball, the bat is obviously into the hitting area. A barrel to the foul line would not only hit the ball, but has advanced thru the hitting area to pull the ball foul, even. I believe I was giving the batters too much and taking from the pitchers.

I have realigned my process to think in terms of "Did the bat enter the hitting zone?", as well as if the ball hit the bat, whether intended to hold up or not, "Would that have hit a fair ball opposite field?". If yes, that's a swing.

Interesting situation.
I agree with both replies above. However, I think the point being made is the ball was already dead on the hit batter prior to the "swing."
Is there an interpretation that allows post HBP action to come into play?
