ThankQ... I think this is also the officer that had just joined 3 days before?
The State Patrol did arrest Jimenez but he was released quickly after Walz (the governor) had words with the agency.
The lawyer for the officer said he was only on the job a few days. But the official line is that he graduated in December with no explanation of what he has been doing since.
The police cars in Minneapolis do have license plates that say POLICE.
Anything else I could offer would be conjecture and/or rumor as the local media seems obstinately disinterested in the questions that have been raised.
