The problem is that the cops know how to delete recordings. <snip>
Fortunately for him, his tablet was synched to some cloud service and he was able to restore the recording.
Well, obviously they don't know how to delete recordings that well.
While I know there's a snowball's chance in hell of the officer(s) in question facing destruction of evidence charges for doing that, I think they should. Oh, it 'wasn't me'? Conspiracy charges.
BTW, here's a
study: 60% reduction in use of force by police officers, 88% reduction in complaints. It's not broken down whether to say that officers are behaving themselves better, or people aren't bothering to make false complaints that would be easily disproven by the cameras, or the people themselves are acting better when they know they're on camera, but it's probably a mix of 'all of the above'.
It also makes investigation into a police shooting a lot faster and easier.
These are the reasons I support the cameras.
