I agree with you that authorities should not abuse cameras to gather revenue under the name of safety and security. It is acturally a state in Australia that are doing it, using tax payers money to install cameras to specifically target the tax payer to gather revenue.
It would be joke of the month. If you place it realistically on a small scale, you pay taxes to spy on yourself so you can fine yourself when you make a mistake. That's what it is. Bit you don't get rewarded, the government does takes millions from it.
And it does not prevent anything, by the time someone is busted on camera and they receive a fine in the mail it's too late, if they were going to maybe, who knows, could cause an accident, as that is why it's illegal, and in the name of safety, it's already to late. It does not prevent anything. Just revenue gathering. Biggest scam ever.
