Should political opponents face DOJ investigations under the opposing party's administration?

Context

The question of whether political opponents should face Department of Justice investigations under an opposing party's administration touches on fundamental tensions in American democracy: the rule of law versus the risk of weaponizing justice for partisan gain. Historically, presidents have broad discretion over their administrations, but norms have generally discouraged using federal law enforcement to target political rivals. This debate has intensified in recent years as partisan polarization has grown and both parties have accused each other of politicizing the justice system.
