Barbie, you said in your own post, "It's in the news every day" Do you think they would put it in the news if an officer did something good? 99% of law enforcement officers are good people, it's the 1% that make us ALL look bad and the media is partly to blame. News is not factual anymore, it's entertainment.
I'm sure you would never find it acceptable to say, Most black people are thieves, But you do find it acceptable to say that most cops are under educated and they tend to bully people. Think about that for a minute.
One of the things I've learned being a cop is that half of what you see on the news is not true or has been embellished. For every 1 bad cop story you tell, I can tell you 100 good cop stories. Please remember who is going to come running to you when you CALL911

And some of us even drive Crossfires!
