True, but Ward was looking for Stewart cart...
It's hard to tell, but it looks like once Ward spotted Stewart cart he moved toward him...
Certainly a dumb ass move which he paid the ultimate price...but did Stewart aim for him and hit him on purpose, I don't think so...
At some point more video will come out with better angles and a clearer picture of what actually happened...
Right before contact did it look to you like he attempted to jump out of the way?
