Presence of FBI counterintelligence ops people would require DHS to request support from DOJ. I wouldn't expect the request to be made, mostly out of pride and because Nappy couldn't possibly convince Holder that subversive activities would be taking place.

If you go, be very careful about exchanging business cards with anyone who purports to work for a company you've never heard of or anyone who asks a lot of strange questions. If you see someone picking up several copies of an attendee list or people who generally don't fit, try to snap a discrete picture. Conversely, if there are people going out of their way to avoid being in any sort of picture or video of the conference, this should send up flags.

This isn't tinfoil hat stuff in the least. I've seen it happen in other contexts over the years.
