At some point when there are more outliers, they aren’t outliers anymore

Moving the goalposts. You’re talking about a scenario before he was apprehended. He was handcuffed. Presumably frisked. How many guns does a person have access to while handcuffed by police? How was he a threat to shoot anyone? Which isn’t the issue here. But for the sake of argument, let’s say he had a gun before being disarmed and handcuffed. Would that justify the policeman’s actions?

Which irrelevant to the incident being discussed. Unarmed and handcuffed. You could, I dunno, ask the people to disperse as a first effort. You could avoid being the ones to initiate violence.

bryozoa has earned a short suspension for some posts that are rather astounding in their level of denial and appeal to conspiracy

Great, you’ve watched Robocop. Will you answer the question?

You like it when police are brutal? What circumstance justifies being brutal?

Anthropogenic Global Warming.

I doubt that this will exert the desired pressure at the national level; that will require follow-through in November. Locally, though, some governments are listening. Others, not so much. (I wonder if de Blasio will bother running for reelection)

Has anyone called another racist here? As far as "ignorant" goes, it means "lacking knowledge or awareness in general" and it's true. Moreno is ignorant of the situation. But instead of learning the history, they are spouting falsehoods. !

Please stop saying things that you haven’t researched, and for which you provide no evidence. I would imagine plenty of people supported abolition only as a tool for ending the war, and it didn’t pass before the south seceded. I don’t see how you can assert a wide movement and moral progress and goodwill as if a switch was flipped and everyone embraced equality.

I assumed no such thing, and did not say anything about “natural appearance”

Undoubtedly people feel pressure to do so, but many are fighting back against this. Your “solution” is rather extreme.

I don’t have that information. I beg you, stop. Why should any minority have to change who they are to conform to bigotry-driven “norms”?

Why does there have to be a motive? It’s not like there is a final goal in mind. Yes. There are people who hate others just because of the color of their skin. They have been taught this hate by others who hate people just because of the color of their skin. You can substitute religion, gender, sexual orientation, and other attributes here. Surely you’ve noticed. You should stop digging.

You should take this advice. You can start your education by reading up on Jim Crow laws and the KKK. Minority disenfranchisement occurs to this day. Then you can revisit your position that nobody impeded blacks’ rights to vote, or ability to engage in business, etc.

There were plenty of slave uprisings. They were not successful. Jim Crow begs to differ. This is incredibly ignorant. Unpacking all of this is beyond me.

The force depends on the mass and cross-section of the drop. It’s not uniform. If it’s barely overcoming gravity, it will move very slowly at first. Not at air speed. A claim you have not demonstrated

Which is not something that should be tolerated with police. 1. The view that they are "scum" should not be tolerated. Everyone is supposed to be equal under the law, and innocent until proven guilty. Everyone has rights. 2. It is not the job of the police to mete out punishment. They are not the judge and jury. 3. He was handcuffed, which should severely limit the use of physical force against him. Some of the destruction has been initiated by people hijacking the protests and inciting violence. A person was just arrested for setting for to the Nashville courthouse. He's white. Others have been caught on film. Most of those arrested in Minneapolis were from out of town. Law enforcement has seen messages on white supremacist sites encouraging members to go and stir up trouble at the protests. On top of all that, the police are inciting violence, too, instead of de-escalating. If people got as riled up about violence by the police as they do about property destruction, this would be far less of an issue.

If I pull out a ping-pong ball and drop it it’s going to fall. There is some size object where the airflow will be enough to support a small sphere of some mass. But without an analysis, you don’t know if a droplet with a virus goes up, goes down, or - possibly the worst possible outcome - is merely suspended because the force of the airflow is balanced by that of gravity. It seems apparent that you can’t do it. You should be asking questions rather than making assertions if you aren’t basing your assertions on anything. Take care you don’t leave yourself open to false advertising lawsuits.

In addition to your lack of air flow analysis, you haven’t shown how quickly the virus, much more massive than air molecules, would get up to speed.

The last straw? For some, perhaps. But I am reminded of the tweet from Dan Hodges regarding Sandy Hook “In retrospect,” wrote Hodges, “Sandy Hook marked the end of the U.S. gun-control debate. Once America decided killing children was bearable, it was over.” (from https://www.miamiherald.com/opinion/op-ed/article33250299.html) I think the same sentiment applies here. Previous incidents, almost too numerous to mention, should have been the last straw — and weren't. Too many have decided this is tolerable, or ignorable. IOW, I wouldn't hold my breath hoping that this one incident swings the pendulum very far. People who have tolerated this kind of violence over time aren't going to be swayed. They are more incensed by Colin Kaepernick taking a knee. Pointing out the racial injustice hurts them more than the injustice. What I think is more likely is that reform comes if we vote the people who have supported or tolerated this kind of behavior out of office, but they will be voted out for other reasons as well. If that happens, this will be part of it, but nowhere close to the whole of it. edit to add: one difference here is Trump stepping in, owing to the protests. His anti-Midas touch might amplify things.

This isn't an analysis, it's a hand-wave. You're making an assertion that isn't backed up by any analysis, and yet, this is a science site. It's not unreasonable to expect that this be backed up by some science and/or engineering. It also assumes you have a room where you can put that amount of vent area in the ceiling. You want a certain result, but have done little to show if such a result is feasible. You haven 't even done something simple, like showing that a 10' x 10' room with air moving at 2 mph / 3' per second in the middle means the air must be moving up to 12 mph at the vent (since it has to be moving ~6x faster if there's no change in pressure) and that this is moving 18,000 cfm through a single room. What kind of system handles that? What kind of pressure do you need in the ducts to get that kind of airflow? IOW, you can't just say "lets move the air in the room at 2 mph" and ignore all of the ramifications and system requirements, like you have a magic wand to make these other problems go away.

Can/will you answer my question? And make no mistake, if you are proposing this mechanism, you are replacing GR.

Gravity isn’t the only effect of GR. How does an “index” give rise to e.g. frame dragging? Or other effects of GR?

Doesn’t matter if it’s obvious to you. Theory says the electron is a point particle and experiment backs this up. Can you transform into a frame where angular momentum goes to zero, the way you can with linear momentum?
