I wonder if police misconduct has declined over time due to their knowledge that cell phones can video their conduct, and because of incidents like this one. This article from last November suggests its too early to know, since these exposes are relatively recent, and the risk of getting caught may not have been fully internalized in bad cops' minds.
See we do have to be careful about this until all the facts come out. It appears that black
and white residents called 911.
See, this stuff always happened. A loud party, out of control kids, cops generally don't draw their weapons but sooner or later you might have to get rough with unruly people. The people at fault are those who don't listen to those who enforce the law.
The liberal argument seems to be that Police don't have the authority to do that. YES THEY DO. Why do you think they carry nightsticks and tasers and guns and pepper spray? For show?
