This is what has been bothering me all along.
I have never known a time when LEO didn't put out a drawing of suspect as soon as possible. After OKC bombing they immediately put out that picture of #2 (not that it did any good).
If they have any idea at all as to what he looks like, they should release it - could save lifes.
Or maybe we could have the population enabled and looking for the next incident and doing something more than the cops have done, who were within feet of the past scenes.
