>> A tense moment caught on video by a Reuters reporter. An African-American police officer sitting alone in a police Jeep in St. Louis, not far from a peaceful rally, confronted by a protester who asks, how do you sleep at night? The message behind the question, as a black man, why aren't you speaking out?
>> I've taken many stands in this country and others.>> I'm a veteran too, but you're making a choice.>> For many black officers, it's a tough choice. Stand with protesters, upset that a white cop killed an often unarmed, black person without legal ramifications. Or stand behind the so-called blue wall, and support a colleague, no matter what the circumstance.
Reuters correspondent, Dan Trotta.>> I think any time there's a police involved shooting around the country, cops of all colors are under a lot of pressure not to turn on their brethren. And with black cops it's particularly problematic, because not only do they face that pressure in the station house, but out in the public, where people feel that they've betrayed their own race by joining the police force to begin with.
>> Breaking the blue wall can come with severe hostilities. A week before the verdict in St. Louis, Detective Sargent, Heather Taylor posted a YouTube video calling for a conviction. The reaction, she said, was so vile we can't even repeat it. Former St. Louis police detective, Bill Monroe, who was out protesting, told Reuters he understands the silence because, quote, nobody wants to be known as a trouble maker.
>> He was a police officer back in the 60s and 70s and, as we're seeing in these protests, a lot of the same issues that were being protested back then are still an issue today. So for that reason, he's not very optimistic.>> But some officers on the force say, the best way to deal with the issue is to influence change from within, and push for hiring of more people of color.
