Chris Hansen just wants you to know the truth.
Yes, he wants to build a new NBA arena in Seattle, and yes, there are those that oppose of such an undertaking for reasons that include the impact stadium events would have on traffic. But Hansen wants to present evidence to those in Seattle that many of the claims are actually to the contrary.
Hansen took to the SonicsArena website to voice his rebuttal to concerns about the building of a new stadium. He presents research as well as gives the reader the ability to look for themselves at what traffic is like in SODO during the times in which games would be played in the new stadium. His only motivation to get people to see his side of the debate, so if you want to take a look, it is all right here.
You should be able to come to your own conclusions after reading.
