No, he should not be prosecuted, investigated, or the subject of any official response. We do have rights, and he was exercising his.
Jones is a moron, but he is in no way worse than those infantile "artists" who deface or offensively represent Christian symbols. They are offensive, irresponsible morons too.
Nor is he any worse than Bill Ayres or any of the other creeps who deface or destroy the American flag.
In no way is Pastor Jones responsible for the deaths of people in Afghanistan. If you wish to condemn him, then you must assign equal responsibility to the news media who publicized his actions, to Hamid Karzai who exploited those reports for political gain, and to the Muslim religious zealots who instigated riots. But, in the final analysis, the only responsible parties are those sub-human wretches who carried out the murders.
The most dangerous and dismaying aspect of the whole affair is the opinion expressed by various government and media figures to the effect that Pastor Jones should be investigated, the subject of other official actions, etc.
That's all I have to say on the subject.
I leave further comment to Christopher Hitchens [here].
