On September 3, 2002, police broke down the door of Brooklyn resident Williemae Mack in a pre-dawn drug raid. Her twin 13 year-old sons were asleep at the time. One, frightened by the noise and the explosive device police used to gain entry, hid under his bed. Police pulled him out and put a gun to his head. Police then handcuffed both boys at gunpoint.
They found no drugs because they had raided the wrong house.
I dont see any police states coming.
But I can certainly do better then your story.
A number of years ago we had an armored car robbery with no leads, Then a disgruntled family member lied about a family member and got the police to conduct a middle of the night raid. They stormed the house, the mother grabbed her toddler and had her in her arms. Then as its told a shot rang out shooting the mother in the neck, she collapsed and was promptly hand cuffed. This is murder and no charges were filed, The cops later admitted the informant lied and they should not have entered the house.
Tragedy strikes at anytime. it doesnt mean vast conspiracy.
