Maryland law enforcement officials in Maryland have issued a warning about the increasing use of smart phones and Web based services to listen in on law enforcement radio transmissions. Gang members, officials warn, are using the smart phone apps to get a jump on enforcement efforts and, in at least one case, to evade capture during a foot chase. The ability to monitor supposedly secure police transmissions poses a risk to officer safety, the MCAC warning concludes: allowing gang members and other to hide their activity, set up an ambush for law enforcement or merely escape in a getaway situation.
