That all started when they banned proper crackers to be sold. The same happened here in the Netherlands. Making them illegal created a black market without any control or restriction. All the extreme heavy stuff is coming in from Poland and the Tsjech republic. When you could buy good fireworks in the shop, nobody bothered to get the illegal stuff. Without any proper border control all that stuff is coming in and causing a lot of nuisance for elderly people, pets and property, but it's a market which was created by our own PC governments.
