There are some very practical things the Government of Canada can do, such as press the Government of Nigeria to constitute credible, independent investigations, demand justice for all victims of police brutality and demand the restoration of fundamental human rights. This can be done by compensating the victims of SARS and by prosecuting perpetrators.
No one has ever been prosecuted for killing, maiming or even assaulting people. There is much evidence of this occurring, and we have not seen an independent inquiry that has successfully brought anyone to book. Also, put pressure for proper training and fair wages for police personnel so people who are well paid and well trained are out on the streets to serve and protect.
The people who are trained right now are not on the streets to serve and to protect. They are out every day looking out for their own livelihoods, and these are people who are armed. When armed people are on the streets looking for their livelihoods, that is like armed robbery.
