Mike Mahar, president of the Amalgamated Transit Union Local 583, was among those who attended court in Calgary Monday morning. He addressed the dangerous conditions drivers find themselves in.

“They work alone, they work isolated, they’re in predictable locations, and people have all the time in the world to wait for the right opportunity,” said Mahar.
