Today, the latest leak of US military secrets, this time by a member of the National Guard,

has once again raised a familiar question.

Why do so many low-level government workers have access to so many classified documents?

It's Friday, April 21st.

Dave, one week ago, exactly, there is an arrest in this case of this major leak of

dozens of pages of secret military documents that have now been splashed across the front pages

of papers around the world and has become a major embarrassment for the US.

And ever since, you have been trying to understand this suspect's backstory and how he ends up

getting these documents in the first place. So, tell us what you've found.

At first, we found very little. The FBI arrests a suspect and they don't tell us much.

Today, the Justice Department arrested Jack Douglas Tashera.

His name is Jack Tashera.

FBI agents took Tashera and DeCustby earlier this afternoon without incident.

21 years old.

Tashera is an employee of the United States Air Force National Guard.
