2. Louis tries to defend whatever Ben's doing by saying that it's basically like random specks of mud or bird shit, but he doesn't seem to realize that intent is a thing. Having random specks on your license plate isn't going to send you to jail, but if it's obvious that you intentionally crafted the specks to defeat the ANPR, that's a whole different thing entirely, even if they vaguely look the same.
3. As much as I don't like ANPR networks or government surveillance, haven't courts consistently ruled that drivers have less rights (ie. "driving is a privilege, not a right")? For instance, the constitution guarantees free movement, but you need a drivers license to drive and police can ask for your license without probable cause. You also can't refuse a blood alcohol test while driving.
