Pre-Crime technology? Really?

So apparently "pre-crime" technology is all the rage now.  Washington D.C. announced that it will soon be implementing this technology to predict when crimes will happen based on the length of sentences, ages of previous offenders, and location (which implies tracking of some sort).  Sounds too wild to be true? Almost like a movie? Well it was - Minority Report.

I don't know about you but tracking someone and plugging information such as age, previous crimes, geographic movement patterns, etc... sounds like guilty until proven innocent.  This is a dangerous road.  Lets remind our representatives that this is not constitutional.
