This is why
Barry Latzer, PhD, Professor Emeritus of Criminal Justice at the John Jay College of Criminal Justice, in a Jan. 24, 2019 article, "Do Illegal Aliens Have High Crime Rates?," available at city-journal.org, stated:
"Nationwide data on crime by illegal aliens is unavailable mainly because most states don't keep such records. For instance, California, with Hispanics making up more than 43 percent of its incarcerated population, provides no information on the alienage of its inmates. Texas does, though, and its Department of Public Safety reports that illegal aliens were arrested and charged with more than 298,000 crimes, an average of over 39,000 per year, from June 1, 2011 to the end of 2018. Though some of these arrests were for nonviolent crimes, such as theft, burglary, or drug offenses, they also include many violent crimes: 624 homicides, 1,911 robberies, and 3,955 sexual assaults (which, under Texas law, include rapes)…
No amount of crime by those who enter this country unlawfully should be acceptable, because it is 'extra' crime that wouldn't occur if our border security were effective."

Steven Camarota, PhD, Director of Research at the Center for Immigration Studies (CIS), in a Jan. 10, 2018 article, "Non-Citizens Committed a Disproportionate Share of Federal Crimes, 2011-16," available at cis.org, stated:
"21% of those convicted of non-immigration crimes were non-citizens — 2.5 times their share of the population…
Areas where non-citizens account for a much larger share of convictions than their 8.4 percent share of the adult population include:
42.4 percent of kidnapping convictions;
31.5 percent of drug convictions;
22.9 percent of money laundering convictions;
13.4 percent of administration of justice offenses (e.g. witness tampering, obstruction, and contempt);
17.8 percent of economic crimes (e.g. larceny, embezzlement, and fraud);
13 percent of other convictions (e.g. bribery, civil rights, environmental, and prison offenses); and
12.8 percent of auto thefts."

What Trump gives the blacks is dignity.
The kommiecrats say to the blacks, you're too incompetent to make a living on your own, and you're too stupid to get an education, so here's what we're gonna do fer you! We're going to take money from the rich white folks who hate you and give you their money! How's that for a deal! Then we're going to lower educational demands so that y'all appear smart and we're going to pay black teachers a lot of money to see to it that you get good grades no matter what! How's that for a deal!
Trump gives them the chance to make it on their own, the same as any white man. That's equality.
Equality doesn't mean the same outcome for everyone. It's the same chance to do something for yourself without the government.
