Join a Protest March in America...this is what you may face...

Police officers try to disperse a crowd Monday in Ferguson, Missouri.

While serving as a U.S. Marine on patrol in Afghanistan, we wore desert camouflage to blend in with our s...urroundings, carried rifles to shoot back when under enemy attack, and drove around in armored vehicles to ward off roadside bombs.
We looked intimidating, but all of our vehicles and equipment had a clear purpose for combat against enemy forces. So why is this same gear being used on our city streets?

On Saturday, a police officer in Ferguson, Missouri, shot and killed 18-year-old Michael Brown, an unarmed black man. In the days that have followed, the town with a population of about 21,000 has seen massive protests in response to the shooting, as some witnesses said Brown had his hands up when he was killed.

Putting aside what started the protests for a moment, it's worth discussing the police response to the outrage. In photos taken Monday, we are shown a heavily armed SWAT team.

They have short-barreled 5.56-mm rifles based on the military M4 carbine, with scopes that can accurately hit a target out to 500 meters. On their side they carry pistols. On their front, over their body armor, they carry at least four to six extra magazines, loaded with 30 rounds each.

Their uniform would be mistaken for a soldier's if it weren't for their "Police" patches. They wear green tops, and pants fashioned after the U.S. Marine Corps MARPAT camouflage pattern. And they stand in front of a massive uparmored truck called a Bearcat, similar in look to a mine-resistant ambush protected vehicle, or as the troops who rode in them call it, the MRAP
