[robots for life]

NJ was my first regional I ever been to it was so exciting! I saw some inconsistencies in some of the final matches. It seems like there should have been some penalties called against the alliance of 103, 25, and 381. Possibly I misunderstood the rules but it seemed as if 25 crossed and line and then backed back over it to avoid another robot, also I saw similar missed penalties throughout the finals in some of the other matches but there seemed to be more in the finals. Also I do not understand the reason for yellow carding 816's entire alliance, I believe it was alliance 2 or 3. Perhaps someone can correct me if I'm wrong or show me a link to some videos.
