I was teaching class last night and a conversation was sparked about pinning your attacker after throwing them. I teach such pins because I used them when I worked security and they are part of the art that was shared with me. I would not use them in a self-defense situation now. I would much rather throw and go or hit them and forget them, another words get out of the situation as fast as possible. I think locking someone on the ground could get you hurt and unless I am a LEO or security, why take the chance. The only other situation would be a loved one out of control. Then I would so I would not hurt them with a throw or strike. What are your thoughts?
