Although this man appears severely drug-affected, nevertheless, he has become a victim, and this victim deserves the protection of the law without judgment. He was ushered onto the road allegedly by the staff of the North Richmond Medically Supervised Injecting Room (MSIR).

Police, however, seemingly have new investigative techniques.

There is apparently no need to interview witnesses or make decisions based on the facts; in other words, there is no need to conduct an investigation, as it was traditionally called, and they can make arbitrary decisions based on nothing much. 

A sceptic may speculate that the investigation was knobbled to protect the MSIR or that the Police want to avoid any complex work. 

But perhaps what the victim is, had a significant bearing.

Maybe the basic police philosophy of executing the law without fear or favour is obsolete.
