Ok so feel free to post actual STATS from Ontario, (I could care less about what a California study shows as I don't live and drive/ride in California. Many US states have no helmet laws but that isn't relevant here, so why would a speed study done elsewhere be relevant here? So post STATS that either show speed was or wasn't a factor in crashes. Yes the police, CAA, Truckers Association all run and support the speed kills message. BUT the police don't say at an accident scene speed KILLS, they merely state it was A factor, not the ONLY factor. If your impaired and going 30 over and crash then there are more than one factor, but your speed is still A factor.
My point that the politicians set the speed limits is people saying it is a "cash grab" Firstly, the police don't set the rules they merely enforce them, therefore it is not a cash grab of their making. Secondly, it is like the lottery is a cash grab, BUT in both cases you have the option not to participate in the game. If you don't buy a lottery ticket, then no cash grab, if you speed within what is considered "acceptable", (generally 15 km leeway), then no cash grab
As for police choosing to do speed enforcement to the exclusion of all other charges, (which is what you implied), this simply is not the case. Normally speed enforcement is conducted on a regular basis by traffic officers. these are dedicated officers for traffic enforcement, when no investigating traffic collisions, then they do other traffic enforcement sometimes speed, sometimes seat belts sometimes distracted etc. Yes it is true it is easier to get a conviction on a speeding charge as it is black and white, (assuming the radar paperwork is in order etc). Rather than blame the police blame the crowns, and JP's, who don't want to deal with "tougher charges" and want the lowest hanging fruit charges.
Yes fine revenue currently goes PARTIALLY to the police service, some is withheld by the province for court costs etc. It takes one vote from the provnical government to change it. It was the province that changed it decades ago, it used to go 100% to the general revenue pool. The Government changed it, they have the power to change it back. So lobby your MPP. To say an individual officer is in a "conflict of interest" is not accurate. To be in a conflict of interest the officer must benefit DIRECTLY from the situation. No officer benefits directly from the collection of court fines.
