I'd also like to say that Langston is carrying a gun in this promo. I hope they do explain how he has come to be able to carry a gun. There are a lot of fans out there who always thought a CSI level 1 was not allowed to carry a gun.

Level 1s can carry a gun. Holly Gribbs did.
Looks like Nick is carrying a gun too and said 'let's go'. So it seems to me that he could shoot a suspect, since you know, he actually has had a career of being a CSI and not Langston, who's only been a CSI for a few months.
Hey, tptb, being in a job for a few months, DOES NOT make it a career.
