Senator GURNEY. What about the other explosives, TNT, and so forth?

Mr. O'NEIL. TNT and composition C-4 are not commercially available in New York City, either.

Senator GURNEY. What about the low order?

Mr. O'NEIL. The low order, as I said originally, black powder could be purchased-black or smokeless powder could be purchased in 1 pound quantities for the purposes of reloading.

Senator GURNEY. Are records kept of that?

Mr. O'NEIL. A record is kept, yes.

Senator GURNEY. They are?

Mr. O'NEIL. Yes, sir.

Senator METCALF. Is a record kept of some of the other ingredients? Mr. O'NEIL. I do not believe so.

Senator METCALF. So you could go into a drugstore and purchase the ingredients or materials in order to manufacture your own product and there is no record kept?

Mr. O'NEIL. That is perfectly true.

Senator RIBICOFF. What is the report of thefts of dynamite from legitimate sources in New York?

Mr. O'NEIL. In New York City? We have had one theft in the last year and a half, and this was a theft at gunpoint. It was a robbery. The CHAIRMAN. Proceed.

Mr. O'NEIL. I was talking about the low order explosives commonly used in bombs.

The last one to be discussed is firework powder. This is obtained, of course, from fireworks, from emptying fireworks, and then repacking them into some sort of suitable container such as a pipe, a very common

occurrence.

These are the incendiary devices that the Commissioner referred to, the so-called Molotov cocktail.

The CHAIRMAN. I don't believe that should be printed in the record; it may be made Exhibit 784.

(The document referred to was marked "Exhibit No. 784" for reference and may be found in the files of the subcommittee.)

Mr. O'NEIL. I wanted to illustrate that there are two main types here illustrated. One uses a simple cloth wick. The bottle on the left is usually filled with gasoline or kerosene, something of the sort. The wick is lighted. The bottle is thrown and explodes and possibly starts a fire.

A more sophisticated version would be to use a firework taped to the side of the bottle, light the firework and this will break the bottle and possibly again start a fire.

For time delay purposes, a book of matches and a lighted cigarette could be placed adjacent to the fuse of the firework.

Next is a more sophisticated type of incendiary device.

The CHAIRMAN. That will be made Exhibit 785.

(The document referred to was marked "Exhibit No. 785" for reference and may be found in the files of the subcommittee.)

Mr. O'NEIL. This is a pack of cigarettes. To all intents and purposes it is an ordinary pack of cigarettes. The only thing that differentiates it from the ordinary cigarette package is it usually has some tape that keeps the flip top closed. We have cut away the back side of this this is

a model of course-and inside the pack of cigarettes is contained a wristwatch and a battery, a photographic flashbulb, and a mixture of potassium chlorate and sugar.

This little device, when it ignites and, of course, it is ignited by the hand of the watch coming around and closing the circuit, lighting the flashbulb. The heat of the flashbulb will ignite the mixture.

This will give a sheet of flame about three feet high and start a pretty good fire. We have had some 30 or 40 of these devices in New York City.

The CHAIRMAN. The next chart will be marked Exhibit 786.

(The document referred to was marked "Exhibit No. 786" for reference and may be found in the files of the subcommittee.)

Mr. O'NEIL. Pipe bombs are a rather common type of bomb encountered in New York City. This is an illustration of such a pipe bomb. It consists of a length of pipe. The pipes, incidentally, are getting bigger and bigger in the passing months. It is capped on both ends.

There are a number of variations as to the method of ignition. This is one illustrated here. It is simply the pocket watch and the battery, and the whole thing is taped to the outside.

The pipe bomb may contain a mixture of black or smokesless powder, or it also may contain dynamite placed inside the pipe bomb. The pipe bomb is rather a vicious type of bomb, because in addition to the effects of concussion, you have the added effects of the shrapnel.

(The document referred to was marked "Exhibit No. 787" for reference and may be found in the files of the subcommittee.)

Mr. O'NEIL. We have had in the last year and a half an increasing number of dynamite bombs. This is an illustration of one type of dynamite bomb that we have encountered.

This particular one is an actual mockup of a bomb we have encountered. This particular one consists of five sticks of dynamite and a cheap alarm clock, a battery and a blasting cap embedded in the dynamite.

Again, when the hand of the clock comes around and makes contact against the terminal which has been provided on the face of the clock, the bomb will detonate. One bomb of this type caused about a half million dollars worth of property damage in New York City recently. The CHAIRMAN. One bomb like that was used?

Mr. O'NEIL. One bomb or a bomb of this type. I would prefer to put it that way. The charge may have been greater than we see here, or the bomb may have been used in pairs. But about a half million dollars worth of property damage was from one bombing.

(The document referred to was marked "Exhibit No. 788" for reference and may be found in the files of the subcommittee.)

Mr. O'NEIL. Here is another simpler type of dynamite bomb. This also has been used in New York City. It consists of several sticks of dynamite, a blasting cap, a length of safety fuse. This is usually used in conjunction with the lighted cigarette and the book of matches as I have illustrated before.

The CHAIRMAN. What you have there is not live dynamite?

Mr. O'NEIL. No, sir.

The CHAIRMAN. Very well, let it be received as an exhibit.

(The document referred to was marked "Exhibit No. 789" for reference and may be found in the files of the subcommittee.)

Mr. O'NEIL. I have mentioned before that when a pipe bomb explodes there is a great deal of shrapnel. I think this picture illustrates some of the things that go sailing through the air.

The CHAIRMAN. The clerk will mark that as an exhibit.

(The document referred to was marked "Exhibit No. 790" for reference and may be found in the files of the subcommittee.)

Mr. O'NEIL. This illustrates the way the pipe bomb breaks up. This is the actual shrapnel which will be collected from the scene.

This is an explosion which occurred either from the illegal possession of dynamite in New York City or possibly while the making of bombs was actually being carried out.

This is the representation of the townhouse in Greenwich Village where we had an explosion and a fire in the latter part of last year. The point of the picture is to illustrate the destructive effects of the explosion. As you can see from the hole in the wall where the two firemen are standing, that is quite a large hole in the wall. That was blown out by the force of the explosion.

This is one floor and that is only half the size of the hole. So the hole extends for approximately two floors.

The CHAIRMAN. Was that a dynamite explosion?

Mr. O'NEIL. Yes, sir.

The CHAIRMAN. Is that where some people were killed?

Mr. O'NEIL. Three bodies were recovered from the wreckage.

(The document referred to was marked "Exhibit No. 791" for reference and follows:)

Mr. O'NEIL. Here is another view of the townhouse. The explosion and fire so destroyed the townhouse that it was necessary to pull down the entire house in order to recover the bodies, dynamite, and so forth. The CHAIRMAN. Are these instances in which you think people were engaged in making bombs and some accident occurred?

Mr. O'NEIL. This is, again, one of our current cases and it is a little difficult for me to make suppositions or to make revelations as to what the people were actually doing at the time.

But I can say that there was an explosion here, certainly, and a fire, and we did recover quantities of explosive components from the location.

(The document referred to was marked "Exhibit No. 792" for reference and follows:)

Mr. O'NEIL. Here is another view of the same premises. This next one is the same location but it illustrates the magnitude of the problem of, first of all, finding the explosives in the wreckage and recovering the bodies, and searching for evidence.

(The documents referred to were marked "Exhibit Nos. 793 and 794" for reference and may be found in the files of the subcommittee.)
