Cwolf, you’re thinking in snapshot terms, when we don’t live in a snapshot. We live overtime.
The point is, reported Hispanic crime rates fell, and they have fallen dramatically. If you’re saying their population increased over that time, that means either we’ve gotten worse at detecting crimes, or
that the population is becoming less crime prone.
And given what we can detect going on among Urban Blacks, who are comparatively worse to police, it doesn’t seem to me the argument “we got worse at detecting” has much going for it.
It’s the same situation at the border. Trump’s own appointed head of CBP says we’re in a 47-year low. He knows full well we don’t see everyone who crosses; his point is that what they do see has clearly fallen, and that it isn’t likely illegals have suddenly hit upon some measure to dramatically hide their numbers.
