David E. Polnitz Jr., Gunpoint Threat, Wisconsin 2024

David E. Polnitz, Jr., 39, of Milwaukee, is headed to federal prison for 36 months after threatening a U.S. Postal Service letter carrier at gunpoint — a violent escalation sparked by nothing more than dog spray. A federal jury convicted Polnitz of illegally possessing a firearm and forcibly intimidating a federal employee, culminating in a stern rebuke from the bench and a message to anyone who targets public servants in the line of duty.

The attack unfolded on June 27, 2017, when a USPS mail carrier attempted a routine delivery at Polnitz’s residence. Without warning, an unrestrained pit bull lunged at the postal worker. Following protocol, the letter carrier deployed USPS-issued dog repellent to fend off the animal. The spray worked — but the real danger was just beginning. Polnitz, alerted by his spouse, stormed outside and pulled a Taurus PT738, a .380-caliber semiautomatic pistol, leveling it directly at the federal employee.

The letter carrier, unharmed but shaken, identified Polnitz without hesitation — in part due to his striking ‘Pepsi blue’ contact lenses, a detail etched into trial testimony. Despite no prior physical contact, the threat was clear, immediate, and criminal under federal law. Polnitz, a convicted felon, had no legal right to possess a firearm, compounding the severity of the charge.

At sentencing on April 18, 2019, U.S. District Court Judge Pamela Pepper didn’t mince words. She called it one of the most serious cases of its kind she’d seen, emphasizing that the victim was simply doing his job. ‘He should never have been threatened with a gun,’ Judge Pepper stated, underscoring the sanctity of federal workers’ safety. The 36-month sentence reflects both the violent nature of the intimidation and Polnitz’s status as a prohibited person in possession of a deadly weapon.

Matthew D. Krueger, U.S. Attorney for the Eastern District of Wisconsin, stood by the outcome. ‘This sentence sends the message that federal prison awaits anyone who threatens a federal employee,’ Krueger said. Assistant U.S. Attorneys Zachary Corey and Benjamin Taibleson led the prosecution, weaving together physical evidence, witness accounts, and Polnitz’s own actions into an airtight case.

Inspector in Charge Craig Goldberg of the U.S. Postal Inspection Service’s Chicago Division added: ‘The sentencing should send a strong message — Postal Service employees are off-limits.’ The joint investigation by the Milwaukee Police Department and the U.S. Postal Inspection Service ensured that a moment of rage didn’t escape justice. For Polnitz, the cost of pulling that trigger — even without firing a shot — was three years behind bars.
