The feds have a license plate attached to someone they want to arrest so they go hunting through available data from license plate readers to pinpoint their location. In that case it's almost certain they're going after an illegal wanted for specific crimes as you're right that it serves no real general dragnet purpose to identify those who are unlawfully present.
I'm sure if they can figure out a way to police mean words with the cameras they'll buy them back in triple the amount. I can't wait to live in Demoltion Man.

So, if you already know who you're looking for, your first move is to use a camera dragnet to find them?
Shoddy police work.
