Surveillance cameras are being installed at Las Vegas fire station entrances to monitor activities and visitors, a plan Fire Chief Willie McDonald announced nearly five months ago amid allegations of sex inside firehouses. This comes as city officials investigate another complaint alleging sexual activity in a firehouse last month. McDonald announced plans to put in surveillance cameras at a May 4 news conference, called after the Las Vegas Review-Journal inquired about claims by a former EMT that sex is common in Las Vegas fire stations despite department policies prohibiting it.
