Should we worry about our National Security?

Today cheaters from Ashley Madison found out that the site was hacked. A big portion of users are in Washington DC., (like Gomer Pyle would say) surprise, surprise!

Any way Asley Madison says that it is true they were hacked but they now have security back. LOL. A little to late.
Anyhow, the hackers say they have information of peoples credit cards, their sexual preferences and kinks and who they have met and job information and home addresses.

So at first I laughed. Karma can be a bit harsh. But then I began to think of how many government officials and contractors with knowledge of sensitive material may actually be on those sites and can now be blackmailed.

Do you think it is something the american public should be worried about?
