For example, assume a witness testifies, "the defendant threw a brick." Taking only one word in the sentence as an example, "throwing" is a conclusion based on the fact of the defendant's having the brick in his hand, holding his arm extended behind his head, moving his arm over his head swiftly in a forward direction, and letting go of the brick at some point when his hand came in front of his body. Also, calling the object "a brick" is a conclusion based on the facts that it was square, red and about the size of other things that qualify as bricks, appeared to be made of clay, and appeared to be heavy. Clearly, if people were not allowed to use any conclusions, their speech would be very strange indeed. These kinds of "everyday" conclusions must be allowed.
