I am not schooled enough in medicine to judge the quantities found in this report, and i do not know what this * exactly means ?
*In this case, the level of methamphetamine determined has not been differentiated according to its isomeric forms. Differentiation of the isomers of methamphetamine is available upon request. 
Again:
" [...] Fowler agreed that Floyd had a normal respiratory rate before he died, and someone suffering from a fentanyl overdose would have a lowered respiratory rate. But he qualified his answer by saying it's possible Floyd would have otherwise had a higher respiratory rate because of the stress of the police restraint.
Blackwell also pointed out that Floyd had a low level of methamphetamine in his system. Fowler agreed the pills found in the squad car were obviously not in Floyd's body, and no pills were found in his stomach during autopsy.
"Correct -- whatever the residual amount in those tablets was, was not in his body," Fowler said."
Be it as it may, if you kneel on someone and he is obviously not in the condition to fight anyone, and he tells you that he cannot breathe, and you continue to kneel on his chest for nine minutes, is that the correct action to be taken?
