The Drug War has already eaten out the core of justice and law enforcement in the U.S.
Snitches, plea bargains, no-knock raids, and overstuffed prisons are all a product of the Drug War. And it all means that the rest of crime gets lower priority and is handled sloppily. This is why leftists are having a field day with the Innocence Project - when cops and prosecutors are this sloppy and operate a system this compromised, of course it will produce injustice.
You don't have to be a "fan" of drug dealers (although the jackboot lickers will accuse you of it) to want a well-running criminal justice system that costs less.
So here we are on FR, the very archetype of the Republican demographic, and the Drug War takes another lickin' from people who, in Nixon's day, were voting for "law 'n order." If I were a cop, I'd be asking "Do I want to lose that constituency?"
I hate drugs. But it does seem that the in the drug war, the drugs won.
