This is just a demonstration of how stupid some people are.
I guess people have the right to show their support in this way. I would guess he'll have no trouble, with his experience, landing a good job, so I don't understand why someone would do this, unless they are just using their money to make a statement.
I still don't know if those emails were foolishly intended as private emails to his girl friend, but he was using a government computer to send them, which technically he should have avoided. I am certain people email their significant others all the time from work to tell them they'll be home late, and what not. If you send a communication using your company or government terminal I suppose you have no privacy; yet i'm old fashioned enough that it bothers me, not that companies/government might monitor email sent over their servers, but that people would release it for political reasons. I still have not seen anything to suggest that his work was impacted in any way by his political views, as pungent and ambiguous as they apparently were.
And of course it must be true that close to 100% of government employees have personal political views. They can't be legally discriminated against for harboring such views, and it is a stretch to say that someone who expresses a political view in an ersatz private communication to a personal friend, even if that friend is also an employee, can be considered as political activity at work. The latter, in government positions, is always both inappropriate and illegal under the Hatch Act. Strzok's ersatz private email was certainly not the kind of political expression that the Hatch Act was intended to address.
I was equally bothered by the opinion of some here on ET that the IRS's Ms Lerner should lose her Fifth Amendment right because she is a Government employee, or even because she is a government employee testifying before a congressional committee. That view, fortunately, did not hold up ; yet it is disturbing that anyone should think that. She had been unwise in becoming a little too conspicuous outside of work in expression of her political views, but being unwise, in and of itself, does not eliminate our Constitutional rights, I hope.
