I am a Texas police officer. It is very common for churches to hire off-duty officers to direct traffic for their services. $45 to $75 dollars an hour is the average rate in my area, but I live in one of the richest counties in the state.
I do agree that this is highly hypocritical. I was a born in Witness. At the age of 19 I knew I wanted to be a police officer, but I also knew the Watchtower stance on being armed. It's why I ended up spending 6 years working as a county correctional officer rather than going right into a sworn position.
