It's just a waste of time and taxpayers money adding more video cameras in Vancouver.
Seeing as there are still no arrests from the riot three months ago. Gathering more evidence will just give the government workers an excuse to "study" more data and delay acting even further. It's already probable that if any token arrests for show do occur the criminals can just say, pretty much correctly, that justice was not swift enough and the charges will be thrown out. Which I suspect is what the Vancouver authorities really want. For this to just go away and be forgotten and hopefully not happen again for at least few years or so.
