You need to keep up with the latest ID research. Evolution can produce irreducibly complex systems. Even Professor Behe has recognised this. According to his paper: Behe and Snoke (2004) a simple IC system can evolve in a small population of bacteria in about 20,000 years.
While it is more difficult, and slower, for evolution to produce an IC system, evolution is perfectly capable of producing IC systems by an indirect route. Professor Behe was correct to say that evolution cannot make an IC system by the direct route. He missed the fact that it is possible by indirect routes.
