Denver cops were caught on camera repeatedly punching a man in the face, causing his head to bounce off the pavement, before tripping his pregnant wife who was pleading with them to stop, causing her to flat on her face.But then they realized another man had been recording them.One cop can be heard saying “camera” before storming up to Levi Frasier, snatching his tablet against his objections, deleting footage and handing it back, confident they had destroyed the evidence.But Frasier had his tablet synched to a storage cloud where the video file ended up before it was deleted, which is how he was able to provide Fox31 with the footage.The news station, in turn, did an excellent job, dedicating more than six minutes to the segment.Denver police, of course, have gone into complete spin mode, telling reporters they had not seen the footage after two days of receiving it, but insisting that Frasier visit them at the station anyway to file a complaint, which is really just an invitation to more intimidation tactics.
