Do we need mandatory sentencing for glassing?

Another night out in Perth and another glassing attack, people are so concerned about shark attacks in the West, but your chances of being glassed at Perth's popular nightlife venues are far greater than being bitten by a shark.

The Broome police officer, still in uniform at the hospital required 18 stitches to his face after a bottle was thrown at him while making an arrest in 2011. 

We need serious action by the government, most likely in the form of mandatory sentencing of no less than three years (with no parole) for anyone involved in a glassing attack with the magistrate having the power to impose a harsher penalty when required. There has been so much press regarding shark attacks, the real danger though happens to be nowhere near the water.
