News tonight reported the explosives were bought from a fireworks store (inside fireworks of course) and that the bombers had only the one gun.
This was reported on the Boston Herald, Huffington Post and several other web sites.

Not sure we will ever know the truth. There was a report last Friday that they had executed the one policeman with his own gun. However today, they are saying the one handgun had the serial number scratched off.
