What could possibly go wrong with this scenario?

A police chief in Paragould, Arkansas is planning on putting police officers in riot-gear & carrying assault rifles on the street in this small Arkansas town. It seems that the town has an increased ‘crime’ wave & his answer for this situation is to have the police patrol the streets at night & stop anyone that they find & demand to know the reason that the person is out after dark & to demand that the person present identification. He claims that the ‘crime’ statistics give him enough reason to do this.
