Agent Carter started with a bang as a fun Marvel spy-thriller. There were many great geek references from Roxxon to Leviathan. Keep up the good work.
The only legal term verbally charged against Howard Stark for Stark technology getting in the hands of US enemies is treason. This certainly is the most serious charge against Stark, but there could have been others.
Treason is “levying War against them [The United States], or in adhering to their Enemies, giving them Aid and Comfort. No Person shall be convicted of Treason unless on the Testimony of two Witnesses to the same overt Act, or on Confession in open Court.” United States Constitution, Article III, Section 3.
Treason is the most obvious charge against Stark and providing advanced weapons to a hostile foreign power would certainly qualify. However, there are two other laws Stark could have violated that do not require the foreign power to be an enemy; providing the information to ANY foreign power would violate the law.
Howard Stark could have been charged with violating the Espionage Act of 1917, which prohibited the providing any information relating to national defense with the intent to injury the United States to a foreign nation. The peacetime punishment for such a crime was 20 years and in times of war, 30 years. Espionage Act, June 15, 1917, 40 Stat. 217, § 2(a). Alternatively, as seen in the Rosenberg case, death.
Stark could also be charged under the Atomic Energy Act of 1946, which provides against providing foreign nations any “Restricted Data” with the intent to harm the United States in prison for life and a $100,000 fine in present day. 42 U.S.C.S. § 2275. “Restricted Data” means all data relating to the “(1) design, manufacture, or utilization of atomic weapons; (2) the production of special nuclear material; or (3) the use of special nuclear material in the production of energy, but shall not include data declassified or removed from the Restricted Data category pursuant to section 142 [42 USCS § 2162].42 USCS § 2014(y).
It is not clear what exactly are all of Stark’s “Bad Babies,” other than one of the weaponized implosive devices the size of a baseball could cause all matter to collapse into a large sphere. While it would require a physics expert, there has to be some nuclear fusion to create that sort of gravity weapon. This sort of weapon arguably would fall under the Atomic Energy Act, which would be further charges against Stark.
