Chernoff asks how Shafer could know if CM used it in MJ's room. Shafer says because he needed a vented IV line. Shafer says the bottle had a spike tear but there was no needle hole in the Propofol bottle. If there had been a needle hole, CM could have used another IV tubing. Shafer says that as this bottle only had a spike tear, there had to be a vented IV line. Shafer says that this is the only vented IV line he saw in CM's orders and he had it shipped to California.
I think he _wanted_ to have it shipped to a residential address in California, but that raised a red flag at Sea Coast and they didn't ship it there.
