etehiver,
The only problem is that you are making an assumption that he had bombs just because it is in the report. What kind? Pipe bombs? Grenades? Cherry bombs?
I don't believe most conspiracy theories, but I do believe we have an over zealous ATF and FBI in this country. And there are a lot of over zealous prosecutors who want to make a name for themselves. This guy may be guilty, but not until he has his day in court.
