Reflection on 'Big Brother Cameras on the Watch for Criminals'

To be able to arrest somebody based on a camera that detects face recognition seems a little ridiculous.
First of all, the cameras that they are using aren't truely accurate. I don't believe that technology, today, is not quite advanced enough to truely have faith in. So how do we know that what these computers are telling us is the truth?
Another reason I don't approve of this, is because it seems a little immoral to be able to use technology to arrest somebody. This shows that, as humans, we are getting to a point where we rely on technology a little to heavily. We should be able to use other methods of solving problems like this.
