I have this prayer that I pray regularly (thanks to a suggestion from my sister):
"Lord, don't let sin remain hidden. Bring it to light so we can deal with it."
I pray it over everything and everyone. It's for myself, my family, our church and school, our city and all it's institutions, and up and up it goes. I pray it for those who are defenseless or who don't have a loud voice; think children, the homeless, the elderly, and those with mental limitations. I pray it over teachers and aides in schools; that they would overhear things they aren't supposed to hear! I pray it over law enforcement; that they would have more than just their natural ability to uncover crime. Yes, I'm praying they would have a crime fighting super power! Crazy? Maybe a little, but I'll let God sort it out. And I pray it over the random citizen like the one in this story:
