none. none. >> reporter: an investigation is under way working to determine how live rounds made it on set. baldwin says he's eager to learn what authorities discover. >> as far as i'm concerned, someone put -- the investigation is going to find out. but someone put a live let in a gun. a bullet that wasn't even supposed to be on the property. this is the thing i hope the sheriff's department doesn't give up on, that they follow this to the ends of the earth. where did that bullet come from. somebody brought live rounds, plural, onto the set of the film. and one of them ended up in that gun. and if the bullets didn't come on the property, we wouldn't be having this conversation. >> reporter: no one has been charged with a crime in connection with the shooting. and baldwin believes he's in the clear. >> i've spoken to the sheriff's department multiple times. i don't have anything to hide. you know what i mean. the facts as i see them are what i have stated on the record. >> you're not worried about being charged?
