An amusing video of a YouTuber dad using footage he recorded on a GoPro to prove that his younger daughter kicked his older daughter, and not him. <br /><br />The footage, filmed in Montreal, Canada on April 14, shows David Freiheit - who runs the YouTube channel Viva Frei - walking to the museum in the city, when one of his daughters complains she's been kicked in the back of the head. <br /><br />No one can work out who's responsible so, later in the video, David slows the footage down to catch the culprit. <br /><br />"There were only three possible culprits, and no one was fessing up," he joked online. <br /><br />"Luckily, the eye of the GoPro never blinks, and the case was swiftly solved."
