Didnt a recent court decision say this was protected Under freedom of speech?

That was for headlight-flashing and was in Florida.

That officer just spent a bunch of taxpayer dollars: http://www.statesman.com/news/local/in-lakeway-a-crusade-aga...

That should be her entire story, that recently in Texas, in fact the state's capital, the same exact thing happened and resulted in a finding of complete innocence of the charges and a suit and settlement for the city. Don't get hung up on her intent, why she's wasting her time like this or whatever, just that here's a cop who just repeated a mistake he should have known not to make, and now the taxpayers have to pay out for it.
