Let me start with this . . .

For illegal alien driven crimes to go down, that means that illegal alien crimes have reached such EGREGIOUS levels, that for those crimes to go down, it only means that the crime rate has sadly reached HORRIFIC levels, instead of just "OH MY GOODNESS, WHAT THE HECK IS GOING ON" egregious levels.

(added after posting):
The number of justifications is endless AGAINST illegal aliens being held responsible for their lawlessness.

Such as, illegal aliens hold their race, as racial profiling, in the face of those who want them to provide their legal identifications, just like Americans do many times during each day.

Hence, illegal aliens hold themselves up as superior to all Americans. An elevation they will not be able to reverse if ever they receive a blanket amnesty that will cover over a majority of their numbers who are active willing participants in thousands of ongoing criminal activities.
(end of added potion).

To explain . . .

Americans in the majority really MUST be more educated about how the criminal mind works. Especially, those criminals who proclaim, in the name of their race, that what they are doing is not a crime.

For a lifetime criminal it's all about framing the LIE so that it appears to be the truth.

Then, all they need is corroborators to justify their LIE, so that their LIE “appearsâ€
