Here is footage of a Black guy, presumably BLM, sneaking up behind an innocent, oblivious White guy and hitting him in the back of the head with a brick. Probably brain damage, and another White life over, because for the multicultural Fascist system, White lives don’t matter. In fact, the attacker’s groupies said it themselves.

“Baltimore police have confirmed they’re probing a brutal attack on a white man hit in the head with a brick. The attacker appeared to have accomplices filming and laughing. However, no victim has come forward, local media report. The victim was hit in the head in the Sharp-Leadenhall neighborhood of south Baltimore on Sunday evening, police told local media, affirming the content of a disturbing video that went viral on Sunday. The victim’s assault was filmed by a group who seemed to be in league with the attacker, shooting video from across the street and laughing uproariously as the assailant’s brick connected with his quarry’s skull. The clip was originally posted to Instagram by user traysavage_, who appeared to be glorifying the assault and casting it in racial terms. “YOUNG MAN YOU GOT KNOCKED TF OUT,” he wrote, in between crying-laughing emojis. “B**CH YOU BET[TER] NOT RUN,” the post continued, adding the hashtag #WhiteLivesDoNotMatter before the more familiar #BlackLivesMatter. The victim appeared to be white and the attacker black, though neither’s faces were visible in the footage that has gone viral on social media. According to the person who called in the assault to police, the two men had an argument and the victim walked away. The attacker then reportedly picked up two bricks and ran to catch up with his prey, surprising him with an attack from behind. It’s not clear whether the victim knew his assailant before their altercation, and all police found when they turned up on the scene was a pool of blood. The attacker fled the scene after incapacitating his victim, and by some reports the victim merely got up and walked away – though it’s hard to imagine how, given the blow he sustained. Residents of Baltimore and strangers alike lamented this kind of violence was common.”

     This tape shows the need for situational awareness, not mindlessly walking in a state of “white” according to Jeff Cooper’s colour code of survival readiness, but being aware of the environment. The White guy did not even need a gun to defend himself; he could have avoided the attack by simply turning around in time, or if there was a dispute, having common sense and not turning his back.

“Combat mindset and the Cooper color code
The most important means of surviving a lethal confrontation, according to Cooper, is neither the weapon nor the martial skills. The primary tool is the combat mindset, set forth in his book, Principles of Personal Defense.
The color code, as originally introduced by Jeff Cooper, had nothing to do with tactical situations or alertness levels, but rather with one's state of mind. As taught by Cooper, it relates to the degree of peril you are willing to do something about and which allows you to move from one level of mindset to another to enable you to properly handle a given situation. Cooper did not claim to have invented anything in particular with the color code, but he was apparently the first to use it as an indication of mental state.

The following is from The Carry Book: Minnesota Edition, 2011:

•    White: Unaware and unprepared. If attacked in Condition White, the only thing that may save you is the inadequacy or ineptitude of your attacker. When confronted by something nasty, your reaction will probably be "Oh my God! This can't be happening to me."
•    Yellow: Relaxed alert. No specific threat situation. Your mindset is that "today could be the day I may have to defend myself". You are simply aware that the world is a potentially unfriendly place and that you are prepared to defend yourself, if necessary. You use your eyes and ears, and realize that "I may have to shoot today". You don't have to be armed in this state, but if you are armed you should be in Condition Yellow. You should always be in Yellow whenever you are in unfamiliar surroundings or among people you don't know. You can remain in Yellow for long periods, as long as you are able to "Watch your six." (In aviation 12 o'clock refers to the direction in front of the aircraft's nose. Six o'clock is the blind spot behind the pilot.) In Yellow, you are "taking in" surrounding information in a relaxed but alert manner, like a continuous 360 degree radar sweep. As Cooper put it, "I might have to shoot."
•    Orange: Specific alert. Something is not quite right and has your attention. Your radar has picked up a specific alert. You shift your primary focus to determine if there is a threat (but you do not drop your six). Your mindset shifts to "I may have to shoot that person today", focusing on the specific target which has caused the escalation in alert status. In Condition Orange, you set a mental trigger: "If that person does "X", I will need to stop them". Your pistol usually remains holstered in this state. Staying in Orange can be a bit of a mental strain, but you can stay in it for as long as you need to. If the threat proves to be nothing, you shift back to Condition Yellow.
•    Red: Condition Red is fight. Your mental trigger (established back in Condition Orange) has been tripped. "If 'X' happens I will shoot that person" — 'X' has happened, the fight is on.
The USMC uses "Condition Black," although it was not originally part of Cooper's color code. According to Massad Ayoob, "Condition Black," in Cooper's youth, meant "combat in progress." "Condition Black" is also used to mean "immobilized by panic" or "overwhelmed by fear".

In short, the color code helps one "think" in a fight. As the level of danger increases, one's willingness to take certain actions increases. If one ever does go to Condition Red, the decision to use lethal force has already been made — the "mental trigger" has been tripped. The following are some of Cooper's additional comments on the subject. Considering the principles of personal defense, we have long since come up with the color code. This has met with surprising success in debriefings throughout the world. The color code, as we preach it, runs white, yellow, orange, and red, and is a means of setting one's mind into the proper condition when exercising lethal violence, and is not as easy as I had thought at first. There is a problem in that some students insist upon confusing the appropriate color with the amount of danger evident in the situation. As I have long taught, you are not in any color state because of the specific amount of danger you may be in, but rather in a mental state which enables you to take a difficult psychological step. Now, however, the government has gone into this and is handing out color codes nationwide based upon the apparent nature of a peril. It has always been difficult to teach the Gunsite color code, and now it is more so. We cannot say that the government's ideas about colors are wrong, but that they are different from what we have long taught here. The problem is this: your combat mind-set is not dictated by the amount of danger to which you are exposed at the time. Your combat mind-set is properly dictated by the state of mind you think appropriate to the situation. You may be in deadly danger at all times, regardless of what the Defense Department tells you. The color code which influences you does depend upon the willingness you have to jump a psychological barrier against taking irrevocable action. That decision is less hard to make since the jihadis have already made it.

He further simplified things in 2005:

In White you are unprepared and unready to take lethal action. If you are attacked in White you will probably die unless your adversary is totally inept. In Yellow you bring yourself to the understanding that your life may be in danger and that you may have to do something about it. In Orange you have determined upon a specific adversary and are prepared to take action which may result in his death, but you are not in a lethal mode. In Red you are in a lethal mode and will shoot if circumstances warrant.”

     In the times to come, Col. Cooper will be seen as more profound a philosopher than any of the wankers at our universities today, parasites on the public purse. As for colours, I exist in code red 24/7, even when sleeping. And, I do not consider myself as paranoid as some folks I know who live in underground bunkers and nuclear bomb shelters, with those who dare sleep, always having a finger on the hair trigger.
