As someone from Atlanta, the police came out hard in defense of this, to the point where I don't feel bad speaking in terms of plurals.

The phrase I believe goes "a few bad apples... spoils the bunch"?

A million people could defend it, but it doesn't change the fact that the act only happened once.

The police in Atlanta, collectively, made a point to hit home how OK it was and how any else of them would do the same thing, with police management saying such under oath during her trial.

They don't get a "only once" pass under those circumstances.

That still doesn't mean you can talk about the act as if it has happened multiple times.

Maybe if you changed your original post to "Police support throwing grenades..." and not "Police throw grenades..."

Multiple police in Atlanta do through multiple grenades. They just only threw it into crib with an infant in it once. But made sure we all knew that they think they did nothing wrong by doing that, and would absolutely do it again under the same circumstances.

When you go out of your way, under oath, to say that your organization systemically didn't learn from the mistake and would absolutely do it again, an "only once" defense doesn't hold any water.

I get your point. It doesn't change the fact that your post is factually inaccurate.

If you said that the Lebanese government was bad because they have all these deadly ammonia nitrate explosions, then it is factually incorrect because there was really only one explosion. Even if the Lebanese government tries to shirk responsibility, or say the explosion was a good thing and they'd do it again - none of that means that all of the sudden there was more than one ammonium nitrate explosion.
