Honestly, mulling over this for a bit, I can't tell if you're saying it's dumb to have a shitty screenshot of CCTV, it's dumb for them to investigate a technical-but-clearly-petty Theft, or both.
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.
For the latter, despite what a lot of people believe, the police generally do respond to reported incidents and generally do follow up on all available leads. The disparity in response for some petty crap from a mega corporate location is due to the robust infrastructure they have in place to observe, record, and report incidents. Even in 2026, most people do not have extensive interior and exterior CCTV in their homes, for example.
"This investigation is kinda dumb and I don't feel like pursuing the available leads" isn't something a patrol supervisor would accept on your report.
