Actually, Walmart keeps EVERYTHING, they don't erase any tapes.<quoted text>
Have your car banged up in a Wal-Mart parking lot by a hit and run driver. Ask the manager of Wal-Mart if you could see the tape around the time your were parked there to try to get a lead on the person that hit your car. First, file the police report, then beg the cop to look at the tape, then beg Wal-Mart to allow you and the cop to look at the tape. The answer is "we'll have to check this out with Benton, Ark. and will get back to you later on." How often do they erase the tapes? Daily. End results, you don't get to see the tape,and some nice asshole of a moron just cost me and State Farm,$1500.00 dollars to repair my car.
They never even delete data from past purchases. They have HUGE data warehouses where they keep it all. This is not bullshit, look it up. Beats me what the hell they keep it for but it is a bit weird.
