Worst DQ of All Time?

[casp0555]

I dont necessarily agree with the DQ but the four horse moved over multiple paths and made contact with the other runner. I fault the jock on the 4 for not controlling his runner as he was headed straight near the wire but his actions with the reins seemed to move his runner to the right. The left rein is slapping the horses neck. Would the slight contact and the jocks actions weigh in on the stewards ruling? Im just asking, I agree with Moses that this most likely would not be a DQ in most jurisdictions, unless of course, it was the horse I wagered on
