At a minimum, watch 100 videos. I did last night, only took about an hour, it's easy to find some to nitpick, some which are ambiguous ... and plenty that are totally horrifying.
If you can watch 100 videos in a row from Greg Doucette's list and say, "the militarization and use of force tactics of US law enforcement are not a problem" then I'd like to hear why you think so given this evidence.
Otherwise you're not speaking from an honest grappling with what these videos contain.
If you did that, and then decided we needed either better laws concerning food safety, or better enforcement of existing laws... where is the logical issue? If someone was to make the argument that a certain tolerance of bad food handling is to be allowed, then we would need to know the rate to know if we needed to make changes, but if the view point is that no restaurant should be engaging in that behavior then I don't particularly see the issue.
