Bernardy came to the defense of his friend Harrison in a fight with Wilson. Wilson started the fight, and after Harrison knocked him down, Bernardy (who was wearing tennis shoes) kicked Wilson several times in the head. Bernardy stated that he did so because he believed an onlooker, Gowens, would join forces with Wilson against Harrison. Bernardy maintained that his use of force was justifiable because he was protecting another (Harrison) from injury.
