If drunk driving is a crime, then anyone charged with it can demand to be tried by a jury. I’ve never heard of anyone tried by a jury in a drunk driving case unless it involved other charges — vehicular homicide, for example.
What’s all this stupidity about drunk driving? The Feds can arrest DiBlasio for aiding and abetting an illegal alien according to U.S. Code. As senior member of city executive branch, he is the ‘top cop’ and is responsible for enforcing all laws. Any assistance to an illegal alien is subject to the law; transportation, food, or lodging, for example.
