Possibly depends on the country. There have been issues in Germany, but we have some pretty atrocious networking laws.

And I guess you could interpret GP’s comment as moral, I was reading it as legal, but there’s no real sign one way or the other.

I take it as a moral argument because awareness of the behavior of abusive police departments wouldn't have changed by looking at the traffic.

Risk obviously would. And it’s about the laws.

But it isn't about the laws, or why isn't that a problem for Cloudflare or Comcast? It's about police departments doing what they ought not to do out of incompetence or a desire to harass innocent people who inconvenience them without violating any laws. Which they could just as easily be doing because of Napoleon syndrome or lobbyist pressure from the RIAA.
