Jujitsu License Plate Tae Kwon Do...Should I?

Tae Kwon Do...Should I? - jujitsu license plate

I began with Tae Kwon Do for a few months and has fallen, but I felt that he did not learn enough. So I took Jiu-Jitsu and took some time, but I did not know had been expected, as much as I do. I thought back to Tae Kwon Do or a dojo in Karate / Tae Kwon Do I have really strong kicks early to know whether someone tried to hurt myself or someone else will not be able to approach me, because I could kick very, very strong. I know a little black belt in karate and Tae Kwon Do and I would not play with them. Then I wondered whether it has the ability to have a "murderer" would help me in the streets? I want a police officer, so that no additional support for self-defense, and my local station offers training outside (I know a few cops). It TKDKarate or a good choice? Furthermore, it was what I do in the meantime to prepare for the training? All the exercises / stretches are best? I discovered that I like martial arts. Get my license soon for transportation is no problem.
