So, what is the “right”/“correct” way to address the situation if they are caught in the act?

Not confronting them or just calling the cops (who will get there long after the deflater has left) just lets them complete their work, perhaps even emboldening them by making them feel unstoppable.

On the other hand, bringing weaponry - be it mace, or a taser, or a bat/crowbar/etc, or even a gun - into the situation is likely to only result in a very bad end for one party (possibly even the one who brought the weapon to begin with).
