Mugger Choke Hold
You may feel you could repel a weaponless mugger, but if the muggers are professional you will have little resistance available to you and you will not see their faces. You will be walking on a sidewalk, maybe even with a friend or a group of friends. Suddenly a mugger will reach around your neck from behind with his/her forearm across your throat and will grab the cloth on your opposite shoulder with the same hand and quickly pull you backward.. The pressure on your throat will stop any outcry. You will be leaning backward off balance and unable to kick or throw the attacker. The attacker will be perpendicular to your body so you may be hit him or her with your elbow on the attacking side. You could use you other elbow to strike backward, so the attacker will grab that elbow with his/her other hand. An accomplice will reach around and quickly remove everything from your pockets and take your purse/briefcase. The attacker will then drop you on your butt. While he/she and the accomplice runs away. By the time you may look around, they will be gone. The entire procedure happens so quickly that your friends will turn and see you on the ground, think you have fallen, and rush to help you. They will probably not even be aware of what has happened.
If you are able to react quick enough, which will be doubtful, you should grab the attacking arm and pull down while quickly thrusting one leg backward into a deep front stance. If you do this quickly enough, you may regain enough balance to throw your attacker. More than likely, you will not know what happened to you until it is all over.
