If they know these people are active criminals they will have no problem citing just cause for arrest and search.
I live in Canada, our gun rules are different than the USA. This week in my city some charges against a dangerous criminal were dropped because the police had a “flagrant disregard for charter rights” (according to the judge) (oir charter rights are similar to American civil rights)
They searched him improperly, and found a loaded, illegal gun. Charges dismissed. If they had handled it properly they could have made the charges stick. What a waste of everyone’s time. Police didn’t respect his rights because they don’t respect my rights.
