The data on shoplifting is highly unreliable. Most victims don't file official police reports because it's largely a waste of time. The large nationwide chain retailers do have accurate data on loss rates internally but they don't release it.
The guy found out that in 2017 Walmart decided to close some stores and concluded "aha! closing SF store has nothing to do with rampant and obvious theft but it was part of that program to close stores".
Except the program ended in 2020 and SF store closing was in 2121. It's right there in text supposedly "proving" it's not because theft.
Plus Walgreen explicitly said it's because theft.
There's willful ignorance involved in parsing this information to conclude that it's not theft.
