You would only get in trouble if the evidence is SO different from what you provided that it appears you intentionally or knowingly filed a false report. Examples:1) The video shows the person did bump into you, but it appears accidental: you believing it was a deliberate push may be wrong, but was reasonable and not a false report.2) The video shows you were pushed, but there were several people around and you thought it was the wrong person. A reasonable mistake, and again, not a false report.3) But if the video shows no around you making contact with you at that time, then you could be charged with making a false police report.
