"with even the government not denying that a file of the worthy officer's list of blatant anti-Semitic experiences at his comrades' hands does exist."
This effectively proves that your theory is wrong. There was a history of complaints. He did not make up the complaints after the fact as you suggest "to save his job". And, BTW, why would you say "I don't believe any of the anti-Semitic stuff?" Do you mean it didn't happen? Couldn't happen? Is there something in the story that suggests fabrication? Are border patrol agents too good to be anti-Semites? Curious to hear your theories.
One fact seems curious to me; his fellow officers stood up and testified on his behalf in the case of the Algerian terrorist, er, I mean speeder. If his fellow officers were all anti-Semetic bastards, they would have remained silent.
(Of course, the force could have been divided among good and bad apples.)
I am always suspicious of substandard employees who file these types of cases. How many times have we seen that the victim was actually the perpetrator looking to either cash in or deflect criticism.
In this case the issue of his removal has nothing to do with the alleged anti-Semitic activity unless you want to believe in conspiracy theories.
There is not enough info here to render a judgment but something does not smell right as he waited until after he was fired to file the action. I am thinking sour grapes. If I am wrong I hope he wins.
