If Peru is right about the amount of crime from the Venezuelans, then I side with them. All these fancy treaties and Declarations of various rights, they are just an excuse to make it almost impossible to defend ourselves against migrant criminals.
I see the exact same thing happening in South Africa, from the migrants coming from other African countries. As in Sweden, the Nigerian criminals are quickly taking over.
A criminal is a criminal, but if they are also being provided sanctuary as refugees, they have even less rights to having their 'rights' respected, when they do not respect the rights of their hosts and benefactors and pay them back by attempting to destroy their society.
