Walgren can blow all the DT theories out of the water on his closing. To believe any of their scenarios, MJ would have just been running around at will with an IV portal in his left knee, condom catheter, rolling an IV pole, taking his oral medications whenever he felt like another dosage..and oh by the way - toss in a bolus of propofol that CM just was thoughtful enough to leave there for him. All of this without CM noticing something was awry. Alrighty then. And during all of this time, where was his doctor?
