Someone who has come to the stage where they have located a seller of explosives and has the money ready to buy them is seriously interested in blowing something up and killing other people in the process.

I have no qualms about their getting nabbed.
===========
There's something we need to work on as a society. We need to negate the idea that the man who destroys something is as capable, intelligent and co-operative as the men (and women) who built it.

The one who blows up a skyscraper has done something that is nowhere near as complicated, useful and beautiful as those who designed it, tested it, and built it.

The punk who squirts his graffiti on a stone wall is nowhere near as competent as those who quarried it and built it.

Finally, the man who goes out with a rifle he could never have crafted and shoots a beautiful wild animal with it does not acquire the virtues of the wild animal, not even if he stuffs it and mounts it over his wet bar.

I figure this applies to that beautiful, high-rising bridge as well. It wasn't easy to build, I'm sure. The crude act of blowing it up will not shed glory on these vicious fools, but they probably think it will.
