The former NSA contractor arrested for improper possession of classified material and Government property is being characterized by observers as neither a whistleblower nor a spy, but rather as a "weirdo." How the industry term "weirdo" may figure in any eventual defense remains to be seen. It appears increasingly unlikely to most that the contractor arrested had any connection to the Shadow Brokers' leaks.
Observers also think it unlikely that the arrest will have any noticeable effect on how the US Intelligence Community uses contractors. Both contract and Government personnel are cleared by the same authorities; both contractors and agencies face similar insider threats.
