[53]           All of this leads me to conclude that the mens rea aspect of s. 129(a) requires the Crown to prove beyond a reasonable doubt that (a) the accused knew the individual obstructed was a peace officer or other person listed in s. 129(a), (b) the accused knew the individual obstructed was in the execution of his or her duty, and (c) the accused either had an intention to obstruct the peace officer or foresaw with certainty or substantial certainty that doing the act in question would obstruct the peace officer.
