Securing a system varies across the country. While some have a full hit of it, others have limited use or none at all. It really depends on who is running the show, your atmosphere is around that region meaning the current and recent if any turmoil, incidents etc and if any agencies have agreed to clear communications such as oem, sheriffs, chiefs etc. While some do use the features fully others choose to limited or not at all. It truly depends on many factors but scanning will always be here and new models as time moves on.
