No it showed Bruce was a good street fighter before Ras. It takes alot more than that to become the world's greatest crime fighter. Such as training with dozens of highly specialized mentors in a wide array of crime fighting skills since the age of nine. Beating up a few thugs in prison is hardly any indication of this.
Ras: Tiger... Ju Jitsu... Panther... you are skilled. But this is not a dance.
Remember that line? It was said when Bruce kept switching styles in his second encounter with Ras. Even though none of them worked because Ras was a better fighter. But the point is, he WAS skilled.
And he didn't JUST beat up a few thugs. He beat up SIX prisoners ALL coming at him at once. I don't care how good of a street fighter you are, you REALLY have to know your stuff to survive a six on one slugfest, much LESS own the crap out of ALL six guys.
Oh, and one more quote.
Bruce: The man had a gun.
Ras: Would that stop you?
Bruce: I've had training.
Now, that could be attributed to the training he's had during the league of shadows... but considering he still looks totally green during that scene... I'm going to conclude that Ras is starting out with him, and he's been trained beforehand.
Either way, the complete ownage of those prisoners plus the scene where Bruce and Ras meet for the second time show that Bruce was OBVIOUSLY skilled before his meeting with Ras.
And besides... Begins and TDK is portraying a very young very GREEN Batman. And the comics Batman wasn't even the "world's greatest crime fighter" during the early days of his career. Ever read Year One? He wasn't perfect, he made mistakes. What made him the "world's greatest crime fighter" was the decade plus expierence on the field.
You call that a courtroom scene? That was a dodgy televised broadcast with no emotional gravitas and what looked more like cordial than acid. Plus it wasn't a scene. It was only about seven seconds.
I guess I should have used a smilie. That line was supposed to be tounge in cheek.
