Here its LOS only too, but you can import the equipment needed for way out of sight with ease and zero chance of not getting it.
Actually there are a lot of examples of this where you can get something thats legal in another EU country into Denmark using regular mail, this is why i say what ever efforts on our behalf go on to try and stop this are waste.
a flick knife are not legal here, actually carrying any knife sized knife are not legal in general, i say screw that rule let people carry what they bloody please. BUT ! if they use that thing wrong, well then society should come down on them much - much harder.
I am pretty sure at least 90% of Danes carrying or wanting to carry a knife, would never use it on another person, so our knife law ruin it for the vast majority of people, all so a few people can do what they will be doing anyway.
Actually if i was to form a political party or again vote for one, well then that party would not come up with anything new, or support anything new before 2 old obsolete or wrong laws was removed.
I think the longest ranges people fly now are around 100 Km, but really the range are not a issue not least with quadcopers / regular helicopters that dont need a runway to take off.
A plane on the other hand are a little more difficult, still you can use any road, and with practice you can also launch out of sight, and so can launch anonymous.
