> What's the analogous conclusion from this to police brutality videos? You watch 100 and begin to think you should never talk to a cop again?

You can do better than this rhetoric question. The analogous conclusion would be that there is a systemic issue with the police and you'd prefer not to deal with them again, by defunding or dissolving the police force (seems to be a current wish by many).

> Sure you can post up a bad conclusion to draw and then attack it. I'm pretty sure there's a name for this sort of thing.

Sure you can pretend it's a bad conclusion when it's about the effect of watching selected videos and how drawing any conclusions from that is naive.

How many videos of police brutality do you need to watch before it's ok to conclude reform is needed?

That's not how it works. The state of the police force isn't assessed by watching selected videos.

That's how it has to work.
