What's the deal with Red Herrings?

By koptursky, in Android: Netrunner Rules Questions

I have a question why play a red herring if it can be trashed for one. I rez it and got my agenda stolen and the runner only had 2 credits> what gives? What am I missing?

It's effect applies even during the run in which it is trashed . It's written on the card.

In other words, that, runner COULDN'T steal your Agenda if they trashed the Red Herrings and had less than 5cr left.
