i've been trawling throuqh some of the horrofic videos coming out of the war in Ukraine, and especially the way the UAF have utilised and adapted some types of small, inexpensive hobby-type drones into lethal killing machines. having lived through the era of various types of explosive devices ( car/letter bombs, ied's, bombs on planes, suicide bombs in backpacks etc..) it seems like a whole new chapter has opened up to bad people to do bad things. Imagine the task of the security services now globally having to factor in the risk of an attack coming literally out of the blue, at any event involving royalty, politicians, celebs etc., and the possibility of mass casualties at a major event. I'm sure the security services will already be ahead of the game on this, but how on earth do you begin to protect against something that can attack any time/any where?? the possibilities are endless.
