It's unacceptable, but not necessarily nefarious.
You have a case, you have a case number. The interface is stupid and you can't paste it in, you have to type it out every time. And every selected camera is another query with that same field waiting for the 15 character code.
You get bored, you type in crap knowing A) people rarely check if there's no complaint and B) you have a case.
I can't say that's what happens with every system, but that's why the video logs look like this on the ones I've touched. Which is also why we captured logon ID and didn't just rely on trusting the manual input.
You know what they fucked with far less often? CPIC queries. Abuse CPIC and you lose your job because if you don't lose your job, the RCMP pulls the police service's access. It should be the same locally, but it typically isn't.
