Maybe.
So, how could Trump be responsible? Well, because the Minn police department is a reflection of Trump's SPECIFIC policy CHANGE on police departments.
"The [Rodney King] riots’ 25th anniversary also happened to mark the beginning of the Trump administration. Jeff Sessions, newly installed as attorney general, immediately set out to undo years of progress on police and criminal justice reform. In April of 2017, a federal judge approved a consent decree—a legally-binding agreement between the Justice Department and a police department mandating reforms that is enforced by a federal judge—in Baltimore, finding that Sessions’ objections to an agreement made under the Obama administration came too late. “I have grave concerns that some provisions of this decree will reduce the lawful powers of the police department and result in a less safe city,” Sessions said at the time. “Make no mistake, Baltimore is facing a violent crime crisis.”
"Though stymied from preventing Baltimore’s consent decree from going into effect, that same week he had ordered an internal review of all existing consent decrees nationwide. Even as Sessions’ relationship with the president turned sour over his recusal from the investigation into Russian election interference, the attorney general kept his head down and pulled back on criminal justice reforms, returning to a tough-on-crime policies that Sessions, a former prosecutor in Alabama, felt should never have ended. (Sessions is running for his old Senate seat in Alabama, but without the support of Trump he is not expected to win the Republican nomination in a July runoff.) The government’s police reform work came to a halt, while criminal justice policies reverted to harsher iterations."
"When Trump finally fired Sessions in November 2018, the outgoing attorney general had one final trick up his sleeve. Before leaving the Justice Department, he quietly signed a memorandum in one of his last official acts all but ending the department’s oversight of police departments. The memorandum made the Trump administration’s de facto policy against new consent decrees official, while extending the same hands-off policy to other areas of federal enforcement involving state responsibilities in areas like pollution and voting rights. Experts predicted that even departments already under current federal oversight might once again act with impunity because the memo undercut the authority of civil rights attorneys to enforce them. Sessions’ memo set policy, but it also sent a message to police departments that they would no longer have to answer to the federal government—not even when when officer shootings draw national attention. "
Sessions’ memo also takes pains to emphasize that states are ‘sovereign’ with ‘special and protected roles’ and that, when investigating them, the Justice Department must afford states the ‘respect and comity deserving of a separate sovereign,'” Christy Lopez, who oversaw investigations by the department into local police agencies during the Obama administration, wrote at the time the memo was issued. “In his view, the Justice Department should be more concerned about protecting states from the burden of abiding by federal law than about protecting individuals from being hurt or killed by the state.”
"Lopez then made a prescient prediction: “As has so often been the case with this administration, we will have to look to the courts, to local governments and to grass-roots political protest and pressure to protect our civil rights from police abuse. Because, as the Sessions memo confirms, this Justice Department has no intention of letting its civil rights division protect us from abuse by the state.”
AND THIS IS THE GUY AT THE HEAD OF THE MINN POLICE UNION
"Trump traveled to Minnesota for a rally last October, Kroll took the stage in a “Cops for Trump” t-shirt and praised the president for liberating his officers from the constraints placed on them by the previous administration. “The Obama administration and the handcuffing and oppression of police was despicable,” he said. “The first thing President Trump did when he took office was turn that around, got rid of the Holder-Loretta Lynch regime and decided to start letting the cops do their job, put the handcuffs on the criminals instead of us.”"
