Late in the season Lions receiver Shaun McDonald did a similair thing after a touchdown and it scared the lady sitting in the front row, she flinched and covered her face. His throw was actually alot closer than Jacobs's throw and i thought wow what if he hit her.
Because you see eventually see everything once in the world, if they dont start charging teams penalty's for this somone will have a throw slip and it will go in the stands and like I said earlier all hell will break loose.
