Reminds me of the NYPD SkyTowers, which from what I've read are generally unmanned and the footage is never reviewed: http://www.ny1.com/Default.aspx?ArID=64500&SecID=1000
The Armadillo is somehow less offensive as its range is lower and it operates in a lower density area. On the flip side, the SkyTowers don't target anyone whereas the Armadillo is very targeted. Is it fair to publicly shame a person or group of people for a crime they are still presumed innocent of? What about mistakes? What about the police chief's daughter's boyfriend?
