When Brown Deer Police Officer Devon Kraemer was charged with felony aggravated battery following an on-duty use-of-force incident, the case quickly became one of Wisconsin’s most closely watched prosecutions involving a law enforcement officer.
For attorney Chris MacGillis, who represented Kraemer throughout the criminal proceedings, the case underscored a fundamental principle of the American justice system: every client deserves due process.
The charges stemmed from a March 2016 encounter in which officers responded to assist a bus driver with a disruptive passenger. What began as a routine call quickly escalated into a violent struggle. During the confrontation, Officer Kraemer discharged her firearm, striking the suspect. Prosecutors later alleged her use of force was unlawful.
As the case proceeded to trial, Chris focused the defense on the realities officers face when making split-second decisions in dangerous, rapidly evolving situations. During opening statements, he reminded jurors of what was at stake:
“She was scared that if she doesn’t stop the threat, either she or Officer Leeman could be seriously hurt or killed.”
After hearing the evidence, the jury was unable to reach a unanimous verdict, resulting in a mistrial. Prosecutors later dismissed the charges rather than pursue a second trial. Explaining the decision, Chief Deputy District Attorney Kent Lovern acknowledged that the State was “not meeting our burden of proof.”
That outcome highlights why due process is so important.
When a first responder becomes the subject of a criminal investigation, public attention often moves much faster than the legal process. But the Constitution requires that criminal cases be decided on evidence, not public opinion. It also requires the government to prove its case beyond a reasonable doubt.
Representing first responders means ensuring those constitutional protections remain intact. It means advocating for a fair process, insisting that all relevant evidence is considered, and protecting the rights of men and women whose careers, reputations, and freedom may be on the line.
Chris MacGillis represents police officers, firefighters, paramedics, and other public safety professionals throughout Wisconsin in critical incidents, administrative investigations, labor and employment matters, and officer-involved shootings. His commitment is simple: ensure every client receives experienced representation and the full protection of the legal process.
The Devon Kraemer case serves as an important reminder that justice depends on careful review of the facts, respect for constitutional rights, and a legal process that remains fair for everyone-including those who dedicate their lives to protecting our communities.
