I have to call bullshit on this one, though. You make it sound as if speeding tickets -- as Burke points out, others can get out of anyway -- are some major abuse of power. What your statement does convey is that you have a real problem with authority figures. I can appreciate that. But a cop who flashes cop ID at a speeding ticket as the pinnacle of evil in society?
Seriously. Let's forget about Enron employees fleecing old ladies out of their heating bills (nothing personal, Mr. E

). Or
politicians who got us into ill-conceived wars where thousands of people on both sides are killed, took no responsibility for it, skipped town, left taxpayers with a bill for
$1.2 trillion (though currently about $450 billion) with no end in sight, and took a new job where he got pay raises for his girlfriend. Or pretty much most of Italy's political structure (let alone Telecom Italia, Inter, and the FIGC).
There's a mutual understanding among people in law enforcement, and a lot of that is essential for survival when you get into multi-district situations, etc. Of course, there's the opportunity for abuse.
But then what job doesn't have what outsiders might call "insider perks" and opportunities for abuse? From Starbucks employees to people who work at record labels to hospital employees. Heck, I just have a Web site with a bunch of espresso ratings in SF and people from all over the country mail me free coffee to check out -- does that make me a corrupt scourge on society?
I understand the slippery slope concern. But zero tolerance policies are not only unrealistic, they are abject failures.
