Do police ignore dope houses in metropolitan areas?*

Drove through suburban Baton Rouge, several times in the last few weeks, notice a house where multiple random cars parking and going into the backyard/rear entrance.

Went to an adjacent business, asked the store owner there, who said it’s like that all day. No one ever goes through the front door.

Given the amount of intel the authorities are privy too, they must know what’s going on.

So they probably ignore it, because at least this way they know where it is?
They are in on it?
A part of town they are instructed not to enforce drug laws?

For the record the war on drugs is dumb, but if I am property(or business) owner I don’t want a bunch of junkies (assuming coke, meth, or heroin) driving around my area.

Any lawyers or cops want to chime in on this?

*no I won’t give the address.
