The same day that everyone agreed "Roadside Safety Checks" (police looking for drunk drivers under the auspices of checking children's carseats at 1AM) was the lesser of two evils (Drunk drivers killing innocent people is a greater evil than everyone's 4th amendment rights being violated).
To a lesser extent, anytime that politicians frame an issue with the two phrases "it's for the good of the public" and "it's not a problem if you aren't guilty", they're generally trouncing a constitutional right, or greasing the tracks for it to inevitably happen.
When it comes to public safety, the American people stand ready for intrusions of all kinds, it is truly for our own good. Government agents are privy to secret information unknown to the public, therefore we have no choice but to submit.
