This is about the USA but here in The Netherlands the police force must apply the principles of proportionality and subsidiarity [2]. According to these articles, it also forms a basis for EU laws.

Quoting: "The concept of proportionality is used as a criterion of fairness and justice in statutory interpretation processes, especially in constitutional law, as a logical method intended to assist in discerning the correct balance between the restriction imposed by a corrective measure and the severity of the nature of the prohibited act. Within criminal law, the concept is used to convey the idea that the punishment of an offender should fit the crime. [..]"

And: "the principle that a central authority should have a subsidiary function, performing only those tasks which cannot be performed at a more local level"

Apply that to the national guard being rolled out, and apply that to masked police officers destroying the windows of a car. There is no probable cause here. You cannot be like that is a person of color I will detain them because they're illegal. You cannot even pull over a random person like that. Why not? Because the crime of being illegal is not proportional to the violence being used. Now, if they were a murderer, then yes. But then they're a murderer who is also illegal. Not the fact that they're illegal itself is the dangerous factor. Moreover, these illegals actually benefit the economy as they're HR.
