NYC bomb attempt

Is it just me or does anyone think there is a risk in revealing the nature and components of the bomb, providing commentary on why it didn't work which in effect gives terrorists information they need to make the bomb work. I sort of see this as a field test to determine how certain materials can get past bomb detection technology used in Times Square. http://www.cnn.com/2010/CRIME/05/05/times.square.investigation/index.html?hpt=T1
