I would have asked:
“What kind of Law Enforcement Officer is concerned with “Constitutionalist”?
Isn’t that the foundation of your oath?”
My understanding is that "Constitutionalists" is a label by police for those claiming that they do not need a driver's license, do not need to file federal income taxes, etc. It is more or less code word to the likes of Black Panther, KKK, Weather Underground, etc.
