Trump wants to reinstate stop-and-frisk policies. The way they were done in New York was unconstitutional and bigoted. His base will like the bigotry part.
from the article linked to above:
“Applied almost exclusively to minorities, the stop-and-frisk tactics in New York became an elephantine government project that wasted time and money, degrading both to the personhood of the men and women who were stopped and to the professionalism of the people doing the stopping.”
from the article:
“In 2013, U.S. District Court Judge Shira A. Scheindlin ruled that city police violated the U.S. Constitution in the way that it carried out its stop-and-frisk program, calling it “a form of racial profiling” of young black and Hispanic men. ”
This Washington Post article notes ” …there’s no real correlation between the use of stop-and-frisk and New York’s reduction in crime.”
