Like unwritten said, These were poorly made. Several things you should improve on is making the camera angles and movements smoother, and not like it's a person running around recording it. Secondly I think there could have been a smoother or even more accurate story line. Third you should make sure your actors do what they're supposed to do more smoothly, and as a side notice, I don't think cops would chase down Armed robbers with a hammer/baton. lastly you should make sure there isn't unwanted/ unexpected audio (clock going off, whatever that random weird sound was throughout the video, and the music from the park.). I do respect your enthusiasm though.
