Again, you are entitled to your opinion, however at odds that opinion may be with that of another observer of politics (usual and unusual).
And, in point of fact, the campaign contribution was not made in "cash." While it was a monetary contribution (probably in the form of a personal check or (more likely) a check drawn on Mr. Felos' law firm account), Florida law (F.S. Chapter 106; Section 106.09) prohibits cash (or cashier's check) campaign contributions in excess of $100. And, as we've so clearly established, George Felos' contribution to Judge Greer's reelection campaign was $250, which (just to save you the strain of performing the arithmetic calculation) is more than the $100 cash contribution limit allowed by law. Goodness.
The point is for a judge to be above reproach. He may not give the appearance of impropriety lest his impartiality be called into question -- as it is over and over and over in this case.
Again, the laws of the state of Florida, which control here--not your opinion or rhetoric--do not consider a campaign contribution from an attorney to a judicial candidate, even one before whom that attorney has an active case, to be improper, nor the acceptance of such a contribution by that judicial candidate to call into question that judge's impartiality. You feel differently. *shrug*
Early in Judge Greer's 2004 reelection campaign, attorney Lawrence Crow authored and circulated a letter throughout the Pinellas and Pasco counties' (the Florida 6th Judicial Circuit is comprised of Pinellas and Pasco counties) legal communities (Bar Association members), enthusiastically encouraging his friends and colleagues to support Judge Greer, emotionally and financially, in his reelection campaign. Given that Larry Crow is also a former Florida state representative (of a district which includes portions of Pinellas and Pasco counties), is very active in the leadership of the local and state Bar Association, and is one of the most genuinely affable fellows you'd ever hope to meet, his very public support and endorsement must have surely been welcomed and appreciated by Judge Greer. Did Larry Crow have an active case (as attorney of record) before Judge Greer at the time of that letter and publicly announced support? Why...yes, he did. Perhaps you've heard of the case--Schindler v. Schiavo. Larry Crow's clients? Bob and Mary Schindler. It had never occurred to me until now that when Larry Crow sent that letter, that what he was really doing was trying to influence Judge Greer on behalf of his clients, the Schindlers. Now I know better, eh? LOL.
The distinction is generally trivial to us non-lawyers, but in the political world, yes, it does look a bit tacky to pay your respects in a brown paper bag.
Lawyers do have a way of gutting their own code of conduct.
Nevertheless, there is an obvious appearance of impropriety. In more honest times, and in a more honest place than official Florida, higher standards would be observed.
