So thinking about that... One the one hand, suppose I log into reddit and see police officers clubbing some people drinking beers (this specific instance was in a foreign country).

Yes, on the one hand, I'm just more aware of a bad thing in the world. But on the other, if a million people get outraged watching a clip like that, it seems it does create a "magnification" effect where potentially the outrage is entirely disproportionate compared to crime that isn't brutal and on video (e.g. rich avoiding taxes) but may actually be much more important.
