As I understood it, the computer was seized after a complaint was filed that he didn't comply with the request for all the emails - they gave him 2 months to release his emails to them, and then seized the computer when he still didn't produce them and made excuses.
If that is the case, it doesn't sound as though they had proof. Giving the guy the benefit of the doubt, let's look at the following scenario: the "suspect" received a request to forward all of the County business emails. He (for this scenario) turned over all of said emails. However, some opponent, or haters, suggest that he didn't turn all of them over as requested. So, they take it to the Court, which confiscates his personal computer, searching for something that doesn't exist. (kind of difficult to produce something that doesn't exist.)
Now what makes sense about that, and what would keep people from doing that to every person in elected office in Florida? Answer: absolutely nothing. Nothing more than the news story on the subject, plants the seed of wrong-doing in the citizens of his area, even if no wrong doing ever happened.
I in no way am stating that the person is guilty or innocent of the accusations, I'm just saying that this is the perfect opportunity to play poliTRICKS, to get someone thrown out of office, or to get someone else elected.
