Why are some stores so touchy about video cameras?

Question

When people try to produce a video while shopping or messing around Walmart or Toys R Us

Answer 1

Its due to loss prevention (theft) and the competitions pricing. I work at Meijer, which is a Great Lakes region store (not sure where you are from if you've ever heard of it) and we do not allow it. They are afraid that you might work for the competition and you may be trying to view their pricing structures. Its all business.

Answer 2

There are privacy issues about filming staff and customers without their permission.
