With the wide net they are casting (and it's as large as possible), it will be difficult to be effective. The span of control is fairly limited and resources are tight. This makes me believe it's a lot less about the stated reason (terrorism) and more about something else.
If the resourced are focused they can be more effective but then you have ask why they can't get a warrant and stay within our civil rights.
Kind of like universal background checks... Gun grabbers are really happy they got them in CO. So how many prohibited persons were charged with lying on 4473s after July 1, 2013? Zero (at last check). They obviously aren't interested in keeping guns out of the wrong hands or those people would have been investigated, charged, convicted, etc... They are interested in everyone getting a BGC for every weapon.
Why can't we ever slip something in one of these "too big to read it all" bills to give everyone a free suppressor?
Because our cuckservative overlords are more interested in currying favor with the Democrats and avoiding having the media say mean things about them than they are in standing up for constitutional liberties.

If there's nothing wrong with having to show an ID to buy a gun, there's nothing wrong with having to show an ID to vote.
