Videos that show other people walking through the property and none of which show Arbery stealing anything. As for the 'neighborhood that he clearly does not belong in' I'll just leave that one alone.
You've admitted that property was stolen. You are now saying that no videos show Arbery stealing anything. It is my understanding that no videos show anyone stealing anything.
What can we conclude from this? There was no video covering the theft of the items at the time they were stolen.
It means Arbery could have stolen them, but we just don't know for certain if he did. My recollection is that it was the theft of items from the house that induced the owner into installing security cameras.
These cameras captured Arbery in the house several times at night, and Occam's razor implies this is very likely the thief.
