And people are disagreeing with you because it's not legal. From TFA:

"California police are prohibited from sharing data from automated license plate readers with out-of-state and federal agencies."

If license plate data was sent to ICE, that's a violation of the law. Sometimes it takes journalism to uncover illegal activities. Depending on how the consequences take place, more scrutiny or civic action may be needed.

But dismissing this as saying "nearly every US law enforcement agency does plate reading" is fatalistic, and in this case, ignorant of the legality.
