Didn't read the article, but I assume the reason is more like, "we don't think it's worth it to spend more than [30 minutes] looking at CCTV footage for a single bike" (assuming 4x speed, adjust the number however you think it works).
Which, you know, does look pretty lazy. But I assume it's more about funding and wanting to spend that money paying cops overtime to crack heads at protests against the government instead.
It's not some ideological pro-theft stance on the part of police.
