there should absolutely be charges pressed.  I played basketball my whole life on traveling teams, jr. high, high school and college.  Only had one issue of a cheap shot (albeit not as blatant as this one).  I took an elbow to the mouth when my team was on a fast break and I was on the other end of the floor getting up after diving for a rebound.  It knocked my front three teeth out.  My teeth didn't break off at the gum-line like they often do, they came out root and all. 

Since this incident, I have easily paid around $10k in dental bills and am finding out now that my body is rejecting these teeth.  So, now I have to get two more implants (I have already had one).  It's been a painful situation with multiple oral surgeries.

After the elbow, the opposing player laughed as he walked off the court and I picked my teeth up.  There was never any remorse or responsibility, so I tend to want to be more harsh in this instance.
