I don't know how you (?) would know all this.
I hope you're correct. I have reported on several occasions the corrupt officials in my city, all involved in trafficking and in it together. But I reported to the FBI and they're trash. Letters to senators got zero response too.
I've witnessed trafficking on many occasions.
Tips to FBI go straight back to local cops. And you know how that ends.
The whole system is corrupt. Cronyism entirely. But you know, it's all supply and demand. Folks gotta have their drugs and their occasional backholes. And the suppliers gotta live somewhere and the police and attorneys protect them and the property owners who house them.
Remember, power attracts the corruptible. That means any replacements are not likely to be much better. Pardon my cynicism.
