You must learn and train realistically to react in the event of a real danger of attack and street blackmail. As you train, you react. The principle is simple. During training, train hard as well as similar situations that can occur on the street in an elevator, garage in a car, bus, night club or other public places.
Remember this always and every day !!!.
Also remember this:
Do not avoid training with weapons because to learn to defend against a knife or a stick and improvised weapons as well as firearms you must know the rules and its use and know how to use it to be able to take the right response if it is used against you.
Don't be a Victim !
No Retreat ... Fight for Your Survival to the End !!!
