Video evidence has limitations and may depict events differently than you recall. The video evidence may assist your memory and may assist in explaining your state of mind at the time of the incident.

You should not feel in any way compelled or obligated to explain any difference in what you remember and acted on from what viewing the additional evidence provides you.
