For the second time in a week, a passenger has attempted to carry a loaded firearm through security at BOI's TSA checkpoint.  It's still not permitted. 

These incidents mark the 12th and 13th firearms that TSA has discovered and confiscated from carry-on baggage this year.  Guns are permitted only in checked bags (if they are unloaded and declared to airlines).

The Idaho Statesman has more on this story and further clarity on requirements.
