That is a minor parlor trick. My wife, who mis merely an apprentice in this life (although a high-ranking angel in the realm of eternity) once stopped all crime in Tampa, Florida for 24 hours with a five-minute ritual. It is not difficult to do such things, however, if you insist, I shall grant such a minor request regarding the city of your choice.

Please specify. In fact, nevermind. I will do you one better. I will reduce all crime worldwide from this moment forward for the next 24 hours. I appreciate you challenging me to do so, as the result will save lives, even though you are motivated by egotism and a desire to "debunk" me.

God/Nature bless you.
