While front running may be illegal it seems that is possible to do front running if you’re properly placed in the stock exchanges. Max Keiser and Hellen Brown discuss this in the video [1] regarding how this can be done by “specialist brokers.”
Your second link has nothing to do with front running. Your first link just reveals Hellen Brown is full of crap.
In the old days, market makers could potentially front run by physically ignoring the proper market ordering (i.e., in a physical trading pit), perhaps when the broker ahead of them in the queue is distracted with another trade. This is completely impossible in an electronic exchange. There is no "front run this trade" message in either FIX or OUCH (the wire protocols used for trading).
