The Las Vegas strip has jammers, as I’m told and they can exercise the use due to its law NRS 493.103 but the FAA is advising the casinos not to use it, because there has been incidents of drones hitting cars. Instead they passed a law NRS 493.103 - NRS 493.109
I kind would like to see Jammers in my worksite. This year, we have seen drones flying into our work zone, and it forces us to land (for extra precautions)
