Joliet police released the following statement in 2024:
“The Joliet Police Department holds itself to the highest standards of integrity and accountability. When these standards are not met, we not only compromise our legitimacy but also erode the public’s trust. The community expects us to lead by example, and when one of our own fails to meet these expectations, it affects us all. Being a police officer is not just a job, it is a calling that requires each of us to live a life without reproach. I expect my Officers to embody the values of integrity, respect, and fairness in both their personal and professional lives. This is critical not only to maintain the trust of the public but also to preserve the honor of wearing the badge. When any officer fails to uphold these principles, it diminishes the hard work and dedication of all those who serve honorably. Our duty stands now to remain committed to transparency and impartiality and ensure that justice is served,” Joliet police said in a statement.
