Even within Belgium they do not have an intergrated police network.
As far as I have heard not even within the different German states.
How can Europe have integrated police with all the different languages?
If a German police car is chaching a criminal, who drives over another European border they are not allowed to follow.
No borders for criminals and others, but for police. They cannot even cross the border and call for the police in the country they now are in.
In Sweden crimes commited by refugees were not even reported openly - only under number 271 (?) so noone would feel discriminated against.
