To be fair, we don't know exactly what they saw on that video. All we know is that there was a car and a squeegee, and that something was done by EA using the squeegee on the car. And that was one juror speaking his or her own reaction.
But it was just one, not 12. It could certainly have been one juror whose personal response was unjustified. Or otoh they could have seen on video something that no one would ever expect to see. We just don't know.
Good points but I think it is VERY clear what they are referring to:
Prosecution said "Arochi used a squeegee to wipe up the back of his Camaro"
Juror: "I've never seen anybody do that"
It is "the act of wiping his car with squeegee". Not a woman's shawl hanging from the trunk, not Christina's shoe dangling along the side.
Juror also was presenting main points how they reached verdict. It was not just one juror's opinion despite using "I".
Also, their response was NOT separate from the greater context ...that is to say, they were weighing what they saw in the light of what else they saw in court, consciously or subconsciously.
This had nothing to do with context. He was not supposed to make a blanket statement like this that implicates anyone who uses a squeegee whether they are related to a crime or not.
* Their saying "Ariochi was cleaning up the crime scene" would have been in context.
* Their saying, "not even car-nuts who love to keep their vehicles shining would bother with this in the middle of the morning while rushing to work" would have been in context.
* Their saying "not even car-nuts who love to keep their vehicles shining would bother with this when there is a damage on the car" would have been in context.
These all would have been right thought processes to go through to give someone benefit of the doubt... But being surprised that somebody would wipe their car with a squeegee...
Leaving this aside, why do you think Ariochi would do this in a petrol station where there are cameras? Hypothetically, would you have done it if you committed a crime? And if so, under which circumstances?
