"What we must also recognize is that the reduction in policing currently in our city and the lawlessness that is happening is due to two things," Omar said during a town hall event Saturday in Minneapolis.
One of them, she said, is that "the police have chosen to not fulfill their oath of office and to provide the public safety they are owed to the citizens they serve."
The lawmaker's comments come as violent crime has surged in Minnesota over the last year, rising 17% in total while setting records for murders.
Omar's approach to crime includes backing a Nov. 2 ballot measure to replace the entire Minneapolis police department with a "Department of Public Safety." The measure would remove the requirement that the city have a minimum number of officers based on the city's population.
Minneapolis, the state's largest city, has had to fight the surge while its police department suffers from staffing and morale problems after George Floyd was killed by a police officer in the city, something some say has fueled the crime surge. Others have pointed to a rise in unemployment and other stresses brought on by the COVID-19 pandemic, noting that other large cities have experienced similar issues.
But Omar pinned the blame squarely on the shoulders of the city's police department, accusing it of being "dysfunctional."
"The Minneapolis Police Department is the most dysfunctional in our state and probably in the country," Omar said.
The Democratic lawmaker blasted the department for a lack of accountability, saying that it is something that "doesn't exist in this moment."
"And I do believe that the current charter that we have does tie the hands of those who want want to have that accountability," Omar continued. "We are mandated to have a specific amount of policing. We are mandated to have this kind of union contract, that you have right now.
"I don't know any other big city in the state of Minnesota that has the charter that we have," Omar continued.
