I've seen a good number of YouTube videos where someone appeared to be videotaping the police primarily to try to make the police look bad. They added their own narrative/commentary to what was being recorded and in some cases, even tried to provoke a negative reaction towards their filming so they could show people "part of the problem".
And if the officer falls for it, then it proves that he was in fact bad! It is quite literally the police's job to deal with asshats, and to deal with them appropriately, fairly, and with care to respect their civil rights. If the officer fails to do that, then he deserves to look bad.
Of course, if arresting the person doing the filming is genuinely justified, then when the public sees the video they'll agree the officer was being reasonable and it'll make the person doing the filming look bad, not the officer.
It makes the cops distrust and dislike the people filming them
Boo fucking hoo. Being accountable is part of the job. Cop doesn't like it? Then he should turn in his damn badge and GTFO!
