TSA announced tonight that during the last year, they detected and
confiscated over 125,000 illegal articles, including but not limited
to guns and knives.

It's a start.

How many people did they arrest?

Because for every so-called illegal item confiscated, there must
theoretically be a terrorist with a terrorist motive behind each
article.

If they didn't arrest anyone, then all the confiscations served no
purpose - no reason.
