my curiosity was peaked when I noticed several cop cars located directly
in front of the store. I then asked the door greeter what was going
on. he then told me they come 4-5 times a day to arrest people
for shoplifting, a violation of store policy.

speaking of "legal opinions", here's one for you. the word or term
"POLice" literally means "POLicy enforcement". they enforce policies
which are dictated by POLiticians. other policies "might" get
enforced, i.e. such as a "store policy", especially if the local POLiticians
own a bundle of stock in the company store.
