In my experience, while bigger corporations are more likely to have the means, they're also more likely to have all kinds of corporate red tape forbidding providing footage when law enforcement arrives (gotta get every rung of the leadership ladder to sign off, maybe even Legal). I've had months between the reported incident and corporate approval to provide the footage, usually a CD.

In situations like those, Loss Prevention "pretends not to notice" when you take a photo of the CCTV freeze frame with your agency-issued camera, and something like this is the result.
