It some ways I am reluctant to offer ideas ... but exploring them is perhaps the best way to find a preventative. The Jihadies are quite cleaver - so they will probably figure out and attack plan on their own... However, one thing that has not been offered is using a proximity detonation of with fragmentation - kinda like the Jihadi’s pressure cooker bomb without the pressure cooker. The copter drone carries one of those large cannon burst fireworks wrapped with shrapnel. The copter drone is guided in as close as possible and remotely detonated... Run up several of these from different angles and I suspect it would have a pretty serious effect - ‘cause you only have to get close.
