Folks there was NOT a post that says an arrest will shock the world. “Shock the world” was in other drops, but none pertaining to an arrest. This is another Anon trap that people keep falling for. Something Q said has been twisted to something it’s not. See this for this posts with the exact phrase you are looking for:

This may be what you are thinking of combined with the “shock” drops:
First indictment [unseal] will trigger mass pop awakening.
First arrest will verify action and confirm future direction.
You need to go back and look at drop 3848 from 2/8/20
It does state that the first will send a shock wave.
It is in relation to arrests
I was a bit confused until I went back and re-read them
Thanks
