As of February 2018 , the Las Vegas Metropolitan Police Department encrypted their radio frequencies ; blocking the public from using police scanners . The Las Vegas Metropolitan Police Department stated that the decision to encrypt their radio channels was made back in 2015 due to officer safety concerns .
