OK, I've been thinking about this story and I do not understand how anyone can buy this.

Pictured are the 2 different types of Milkshake machines that I could find.

If the machine was type one the operator would have had to make the SAME CLEANING MISTAKE 3 times in a row.

So if they did it 3 times in a row incorrectly, one would assume they did it wrong their whole shift thus poisoning many more than just the 3 cops.

Type 2 seems to have a built in tank on it and if they were using THIS type of machine the entire contents of the tank would have been poisoned and… again more than just the 3 cops would have been poisoned.

Am I missing something here?
