Here in Italy the first one to learn and adapt is always the mafia. The state is so clunky and unnecessarily complicated that it takes ages for it to change and adapt its ways, once this happens the mafia has already changed and transformed to keep away from the law enforcement hands as much as possible.
Nowadays mafiosi do not go around in poor clothing with weapons on them, the wear nice suits and briefcases filled with documents to keep on their shady businesses as they did from the Borbonic times
I am a “regular” flyer and a stoner and I never fail to bring with me a sample of devil’s lettuce when I’m leaving for extended period of time and never once I’ve had any issue bringing my hazardous material with me.
One time I even embarked with a small firework in my wallet I forgot I placed there after a party and none bat an eye.
