There is nothing like ethnic group criminality.
Ordering any ethnic group to leave a certain location or not to exercise their fundamental right of lawful assembly on the basis of alleged criminalities perpetrated by some members of that ethnic group is wrong, both legally and morally.
Legally, what should be done is to apprehend the culprits and deal with them within the ambits of the law.
Morally, if all members of that ethnic group are asked to leave or not to enjoy their fundamental right of lawful assembly, one would have meted injustice to those who are not involved in the alleged criminality.
