This gentleman had enough of the conduct of the DP District Attorneys who protect criminals and destroy law and order in communities. He introduced policing programs that reduced Murder and crime rates massively - but he got no support of the DA's setting criminals lose without bail within 24 hours.
Now analyzing what political implication for the Democratic Party could be - as the Mayor is a Black there goes 500 000 Black votes, The Black community are vulnerable and suffer badly from the activities of criminals and they will follow the Mayor's example. The extreme leftists running the DP at present is destroying the Party from within.
