Crime is a people problem. If you understand nothing else about crime, you must understand this — crime is committed by people. It is not committed by inanimate objects, and while data on criminal activity can be charted as a trend over time, trends don’t commit crimes, people do.
There is a word for people who commit crimes; we call these people “criminals” and, if anyone is interested in investigating trends, one trend is fairly consistent — most violent criminals are repeat offenders, and will not stop this behavioral pattern unless they are locked up in prison.
Keep all these facts in mind the next time you hear Democrats or the news media (but I repeat myself) discussing “gun violence” as an issue. Democrats do not want to discuss crime as a people problem, but rather as a gun problem, because (a) most gun owners are Republicans and (b) most criminals are Democrats. Or, that is to say, the violent crime problem in America is largely concentrated in urban areas where Democrats get the majority of the vote.
