Trying to trap people who have leverage in a bind is a losing proposition. You can't trap people in a bind unless you have leverage.
I am just saying that yet another threat to functioning democracies is coming round the corner, and weirdly, speeding cameras are the canary in the mine.
Wait till the iris scanner that lets you in the office building also does blood alcohol / cannabis testing.
If some people are "above the law", not that they can afford good lawyers, but that the laws are simply not applied, rather than applied and failed, then that presents a crisis for democracy.
If it is visible that these laws are not applied (and presumably will be as everyone gets caught automatically) then society can either stop being democratic, or enforce those laws.
This is I think the key.
Technology gives us the ability to catch everyone.
Speeding is the obvious example, but Facebook, lifeloggers, mobile GPS will help us auto-catch far wider ranges of crimes.
So if we can catch everyone, and log that data, but only prosecute, for sake of argument, those of Hispanic or Afro-Caribbean descent, will the democratic process choose:
None of those are great choices, and vary depending on the crime. But I suspect 3. is always going to be a socially unacceptable - but it is the status quo now (5% of US Blacks in prison vs 0.7% Whites - what happens when that equalises ? Which way will it go - 5% of the whole of USA?)Interesting.
