Acquiring large volumes of agents (fertilizer, etc) to make bombs and known biological weapons trigger monitoring NSA software.
If you think about, provided a set on inputs (scraping internet commerce traffic, map reducing credit/debit transactions), and making the assumption that a majority of domestic terrorism leaks significant swathes of information (angry people usually aren't totally silent and throw indicators well ahead of time), and that only a small number of pepple fitting a finite set of psychological profiles capable of said acts, one can come up with a reasonable model for detecting regions and topics to focus on for intercepting domestic terrorism.
It won't be foolproof, but it is not unreasonable to assume a form of such is in production.
Bio-agents require specific expertise and materials. Corrosive simple chemical agents require expertise in effective dispersal and saturation.
An increasingly limited set is generated for successively more complex but conventional terrorist plots.
