OK,
so why is an unknown person on their porch in the first place?
Better security measures might be needed?
My guess would be that the schitbird‘a dog ran up on the guy’s porch, the schitbird went up after it, smacked it around and left. Probably about a 20 second episode. Most of us probably are not willing to put the “security measures “ in place that would prevent that. It’s not like the schitbird was in the house.
