BY: BEN SHAPIROThe unrest surrounding federal immigration enforcement in Minneapolis did not arise by accident. It begins with the systematic obstruction of federal law by Democratic leaders in blue states and cities. This has collided with the political reality of immigration enforcement. This is the paradox of law enforcement: Americans say they want law and order, but they recoil from seeing it enforced in real time. State and local officials obstruct federal law, enforcement becomes riskier and more visible, and then federal agents are blamed when things go wrong.
