Inspector Tunney has written a most interesting book. Much of what he tells I knew about at the time, from conference with him, or with Major Scull, Colonel Biddle, or Major Potter, and some of the events described I had intimate knowledge of because of personal attention to the cases. Some, however, I personally know nothing about, as they have taken place since I left the Department on January 1, 1918. And a vast amount of good work, of real public service, was done by Inspector Tunney and his men that is not touched upon in this book, that probably will never be written, since, though of great value to the public peace, it lacks some of the dramatic features which characterize the tales that are told. No one can read the book without seeing how brutally active our enemies were here in this country, even while we were at peace with them, how they flouted our neutrality brazenly and contemptuously, how they busied themselves through their accredited officials and their many secret agents in trying to paralyze our industrial life. Their deliberate effort was to prevent the shipment of all vital supplies to the Allies, and they sought this end by fomenting labor troubles, by burning factories, by blowing up ships. It mattered not the slightest to them that in this kind of activity they destroyed the property of a people at peace with them, nor did they give a deterring thought to the fact that they were maiming and killing human beings with their burnings and blastings. It did concern them, however, to keep things dark, to work under cover, so that they might continue this underhanded war against us without being found out. It was the warfare of the savage, who knows not fair play, who is guided by no rules or customs, who strikes down his enemy in the dark, from behind. The lessons to America are clear as day. We must not again be caught napping with no adequate national Intelligence organization. The several Federal bureaus should be welded into one, and that one should be eternally and comprehensively vigilant. We must be wary of strange doctrine, steady in judgment, instinctively repelling those who seek to poison public opinion. And our laws should be amended so that while they give free scope to Americans for untrammeled expression of differences of opinion and theory and belief, they forbid and prevent the enemy plotter and propagandist.
