Fire inspectors in hot water

I'm waiting to hear back from the press person at the Chicago Fire Protection Bureau about the eight fire inspectors who are in deep trouble for working on weekends. Here's a Chicago Tribune story , but it doesn't give much detail. Seems these inspectors were coming in on weekends to test sprinkler systems in several of this city's big buildings. They were paid by building owners to do this, that report said, instead of by the fire department. (The report does not say how much they were paid.) Building owners were doing this because it's more convenient for them. Apparently, testing involves taking the water pressure away from the building, and that's something owners want to avoid during the work week.
