CRIMINALS DESIGN OUR LIFESTYLE.
Here is one of many things forever to be in our lives - MASSIVE BARRIERS - where large groups of people gather. The modern criminal mind wants to destroy and create fear in large numbers, and these barriers become subliminal reminders to enrich our life of fear.
We see things like this, question it, feel it's absurd, necessary, remark about how life has changed and move on. Slowly barriers and restrictions become a acceptable part of our lifestyle. Just as screening at the airport has become a willing invasion of our privacy and at times even to the level of severe lack of logic or consciousness. People are trained to be robotic and answer to the highest order which placed them in positions to observe, evaluate and direct human traffic.
