This is the first thing I've read that actually increased my support for the widespread use ALPR technology. Every illegal alien in this country is a criminal, by definition.
Illegally entering is a criminal misdemanor, so they aren't the same thing.
Unless there's some international border in Sunnyvale I missed, I don't think the ALPRs will catch any illegal entry.
There is a big difference between overstaying a visa for a few weeks and illegal migration.
