No, I've been in this situation as a victim. My bike was stolen and they said it would take hours to search the CCTV. I told them about binary search, they didn't understand.
Yeah, seriously. What is even the context of this? We have no idea. The cops might have been like "We need a warrant to look at that footage you idiot."
Whoever owns the camera presumably has an interest in reducing/solving crime in the area (why else have cameras?), so they would likely be happy to make the footage available to police if asked nicely, with no warrant required.
Yeah, in general, but not necessarily in that circumstance. A lot of time talking to tech people (I'm a softwar engineer) they can can be smug about this while leaving out important context.
