Once again you ignore how hiring non-citizens as police officers apparently violates the Fourteenth Amendment's "privilege" clause.
As I noted elsewhere, our Constitution commands:
“No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States.”
Being hired by government as a police officer is a "privileged" type of employment and is confirmed in a Executive Order which dealt with
“Security requirements for Government employment” and begins as follows:
"WHEREAS the interests of the national security require that all persons privileged to be employed in the departments and agencies of the Government, shall be reliable, trustworthy, of good conduct and character, and of complete and unswerving loyalty to the United States; and
WHEREAS the American tradition that all persons should receive fair, impartial, and equitable treatment at the hands of the Government requires that all persons seeking the privilege of employment or privileged to be employed in the departments and agencies of the Government be adjudged by mutually consistent and no less than minimum standards and procedures among the departments and agencies governing the employment and retention in employment of persons in the Federal service . . . "
Consequently, the State of Illinois, or Tennessee, by extending the “privilege” of being employed as a police officer to non-citizens, is an obvious abridgement of the "privileges" mentioned in the Fourteenth Amendment in that for every non-citizen hired by either State as a police officer, there is one less employment opportunity for the citizens of those States to be hired as a police officer, thereby creating an abridgment of this privilege for their citizens.

“If aliens might be admitted indiscriminately to enjoy all the rights of citizens at the will of a single state, the Union might itself be endangered by an influx of foreigners, hostile to its institutions, ignorant of its powers, and incapable of a due estimate of its privileges." - Joseph Story
