Just watched the walmart documentary - what a rotten company. Apparently walmart parking lots are among the finest places to commit crimes - no security to speak of. The crooks and rapists know this too. Crime rate in the lots is sky high.
OTOH, security is a little better if the store has crushed the union. Mention 'union' and they'll install $100k+ in cameras and surveillance all over the store and parking lot and use it until the threat passes. Then they stop manning the cameras again.
Walmart needs to face a significant drop in sales and even more opposition to new stores. Shopping walmart is supporting slavery.
