the toxicology report is gonna exonerate the cops. As it probably should. Then entirety of the various police body cams show Anderson acting in an incredibly erratic manner, one that can immediately be presumed to be indicative of a narcotic stimulant. He's extremely figgity, cant stop talking, and very emotive. All that combined with a 'yep, coroner found 'insert drug here' in his blood stream' and its a done case. Guy high as fuck gets restrained, and has a bad reaction to the drugs in his system combined with adrenaline from police encounter.
