A brief expansion of my parenthesis in my previous post:

Abraham Lincoln is generally credited with doing two things, preserving the Union and ending slavery. Logically there would be no relationship between those things for which he is remembered and the situation described in the song: Lincoln was not involved in creation of the Bill of Rights, the constitutional basis for the Supreme Court's protection of the rights of the citizens against arbitrary arrest, against torture, against "illegal search and seizure," the right to representation by counsel and trial by a jury of the citizen's peers, protections which justified the Court's rulings like Miranda (arrestees must not be denied counsel and must be informed they have the right). Such Court decisions are seen by conservatives as handcuffing the police.

So the only thing Lincoln did that could be related to the situation described in the song--and then only by assuming the murderer was black--is ending slavery. If blacks were still slaves, the song seems to me to be saying, our streets would be safe. The only thing deep about the song is the fog Junior is trying to spread over his own racism by pretending he is honoring Abraham Lincoln.
