Given that rear end crashes are typically less severe than right angle crashes and the fact that this negative side effect can be rectified using mitigating strategies such as improving signage and education about the functioning of the photo cameras, it appears the photo enforcement safety program has had a positive net effect on traffic safety in the city of Winnipeg."

I'm not sure what kind of point you're trying to make here because all this quote does is contradict your whole argument. How closely did you read it? Even if you read the report by The London Road Safety Strategy, which is brought up in the London meetings, no one is denying rear end crashes increase.
The London Road Safety Strategy wrote: Studies show that angle collisions, which are usually the most severe type of collision, are reduced by 25% when RLCs are used. The number of rear-end collisions may increase up to 15% as more drivers are stopping at the red signal. Overall there is a net safety improvement and a positive overall safety cost benefit.
The point made in both quotes is that while rear end collisions increase, angled collisions decrease. So what they are saying is, would you rather be rear ended by a braking vehicle going the same direction or hit on an angle by a car going a different direction at a higher rate of speed? It's like the argument that seat belts and/or air bags increase chest, neck, arm, and head injuries while the alternative is you're ejected from the windshield and you're dead.
I really don't have much of an opinion on red light cameras. I've never received a ticket through one. I can't say i've seen a "cheap" camera ticket given where I would have rolled my eyes. Probably all the rlc tickets i've seen through this forum were more than well deserved. Going through a red light is stupid, no matter how late you are. I can see the argument for someone who doesn't fully complete a stop on a right turn (even though illegal), but the cameras are good at filtering out those who may roll versus those that go now and ask questions later.
That being said, you're not exactly making great arguments. They don't give tickets for rolling right turns on red (unless you consider never slowing to below 20-30km rolling), they don't increase insurance rates, and no one is denying (not even the City of London) that rear end collisions increase.
