Let's remember the 70's. We went to the cinema and watched all kinds of movies. If somebody was shot there, he fell and the game was over. Today it is different. Heads cut-off, flowing blood, sound effects, torture of women, etc. And if possible, they repeat it all in slow motion. A video game in the hands of a five-year-old child is also the same. He wins when he shoots everyone. Enjoying it, getting used to it and calling it a game. Why is this all? Because it can be sold. We should not speak about movies or games, but about goods, because interest is embodied in the revenue.
The kids grow up and the fun they experienced in their childhood will be tested with real weapons. Meanwhile the masterpieces of cinematic art that Hollywood floods the market, confirms the acceptance of violence. And Hollywood is copied. This is a pattern that will bring thousands of products made by Indian, Chinese and other film industries to the market because it can be sold and is a blockbuster. The more plastically and sensibly manifestoes the tortures, the torn out inner parts, and the bloodshed the bigger the blockbuster success is.
If this psychological preparation is accompanied by possession of weapon publicly, do not be surprised at today's events. If arm-possession were allowed in China, India and elsewhere, there would be similar cases, so it is unnecessary to ask why school massacres and street shootings occur in the US.
If blood is so spread in the public mood, manipulating it for further purposes is already very easy. I don't want to go through the reasoning process and get to ISIS, Al Qaeda, the Mexican drug wars and the industrial production and use of violence. I don't believe in conspiracy theories because I am convinced that not the plans of an invisible background power are being realized. I simply see that there are no brakes and pushing people towards their instinct-life brings a lot of revenue. Revenue overrides everything else. Then, once a situation is given, politics comes and sets its own revenue and interests. They pretend to save us, but in order to save us, they also produce the situation that they will save us from, if we pay. The control is ceased, brakes are not working. The case, what for a mouse is a life-and-death fight, for a cat is a game. They are the cat and we are the mice.
Are you expecting from me to tell what the solution is? I don't know the solution. It is only possible to recommend a solution for which man has the means. I have no such means. Should I call the attention of politicians? It is needless, because they are the winners of the process. Church leaders? Why? They are even worse than politicians. They are the ones who even set up fire in order to hate each other. There is no solution from outside. The solution could come from the masses of consumers if they had such a need. We are the consumers, the means. If we do not consume, interest disappears. The world will only change if we change ourselves. Allah offers us the solution:

…Verily never will Allah change the condition of a people until they change it themselves (with their own souls) … (Quran 13:11)
