There should be another option, "Not enough information to know 100% for sure."
While, yes, it does appear that there is an infraction being committed, there are other factors that play into it.
Was the ball tipped at the line of scrimmage?
Has the ball already been knocked away?
Was the defender knocked into the receiver by another offensive player?
The answer to all these questions is probably no, but unless we know for sure, a determination of guilt based on a still photo is unfair.
