No. It is not and to claim otherwise is hyperbole. The key difference is police stopping and/or questioning people en masse without reasonable suspicion is in fact illegal unless under extreme circumstances. Simply noting everyone’s license plate is wholly legal, and more importantly for this conversation, is drastically less intrusive and qualitatively different from a so-called dragnet. You don’t get to just conflate the two scenarios to better fit your personal preferences of what is or is not legal.
