Whether or not JKD is "complete" is a difficult question to answer. How can you judge accurately when the art is conceptually based? It gets a bit tricky for me, but I'll gladly accept corrections on that.
As far as street fighting goes, I'll answer your question with another question. Are *you* appropriate for street fighting? I'd like to offer that it neednt necessarily matter which MA you practice, but whether your mental and physical reflexes are quick enough to use them. At the end of the day, you could have trained for years but if you're not careful someone could thwart all of that with a sucker punch. Nobody is perfect
