The sad thing is that in a free America there is nothing there that is not able to be obtained legally. This is the first article I have read where he may have been a *prohibited* person. Even if the grenades were live it is possible to obtain them with the proper stamps, etc. The first time I read an article about this he was subject to a search because of the "grenades" and the other stuff was found as a result of that search.
On another note, he lived in Richmond, CA, that alone is reason enough to have that type of collection.
