No tape. Just a description of what is on the tape given to the judge by the prosecutor in a pre-trial hearing. There are links in the article you can follow to find out details of the attack.
Thanks for your neutral, fact-finding approach. Others have already made up their minds without seeking more information. Of course, in no case did the customer have any basis for attacking the cashier physically. But there is much more to this event (given here) that illuminates the attitude of the attacker.
It seems clear that there is a third hand seeking to exploit this incident, through bearing the tremendous expense of defending the accused attacker, who has demonstrated neither shame nor regret.
I wonder who is backing of the defense costs? That's where the real story is, IMHO.
