Joining @OutFrontCNN , @CNNTonight and @cnni for what we know and what we don't. Few points: mutilation of fingerprints is behavior of deliberate attacker, premeditation, assassins and spies type stuff. Likely expected to be killed. 1/

Follow on explosive attack was directed at first responders. Since didnt detonate, will be treasure of info including purchased materials that can lead to surveillance cameras. 2/
Motive still unknown but police would want to shut down any political motive theory and that they haven't done so simply means it's an open question. That's not good b/c by now there were so many witnesses who would have known who he was. So likely he was stranger. 3/
Also another instance of why these first responders training are so important.
