it's kind of like in the netherlands,if you dont give them a reason to stop and search you,you dont have to worry very much.
things have change a lot since the refugees started moving in,not the positive way.
I have the feeling that in the Netherlands the knife laws got more strict when cities grew bigger and bigger and some city subcultures are quite violent. Some groups of refugees and immigrants that moved in did influence the development of the knife laws, but I think it is not the only factor and certainly not the main factor. Just look for example at the explosion of the amount of violence of soccer hooligans. Some soccer games are nowadays cancelled or played without fans of the visiting club, to prevent big hooligan fights.
Some people here just can't deal with freedom and I have the feeling that this group of people is growing each year. I think this is also part of the government which takes a step back. People were very much used to the welfare state where the government took care of them. Now that the government is taking a step back, people have to take more responsibility themselves and for some people that is difficult. That is the group of people that is now wanting a strong leader to lead the country.
I further think some politicians think that if you take away knives and guns from citizens and introduce more and more restricting laws, the society will become more safe. In my opinion they are ignoring the fact that criminals ignore laws.
