Will the FBI be attending CPAC, as so to arrest the the balance of capital insurrectionist/ rioters? ?

No, I think they will be busy interviewing and investigating the Capitol police for this disastrous handling on the situation and their failure to accept the backup that the Trump administration offered them.  "February 19, 2021  

At least 35 Capitol police officers are being investigated and six were suspended following the U.S. Capitol breach on Jan. 6, officials said on Thursday night.

“Our Office of Professional Responsibility is investigating the actions of 35 police officers from that day. We currently have suspended six of those officers with pay. Acting Chief Yogananda Pittman has directed that any member of her department whose behavior is not in keeping with the Department’s Rules of Conduct will face appropriate discipline,” the U.S. Capitol Police said in a statement to local news outlets.

Would not surprise me the FBI has become a very political group and are not trustworthy to implement the law as written. They were once highly respected and the most trusted law agencies in the world but now appear to be a  democratic hit squad.

No, I think they're busy putting together their case against you for interstate child molestation with young boys.

 Many decent people have declined to attend. Pence was the latest. Fat Boy is going and some are boycotting. 

Never can tell. Someone is probably watching.

I think the FBI needs to be dealt with once and for all. This targeted effort against right wingers has been noted and rejected.
