Activists should be charged with jury tampering for handing out jury nullification literature on courthouse grounds. It is the people's right to know that jury nullification exists, however that knowledge should not be shoved down their throats. They should be able to find out about it on their own time. If that knowledge it shoved in their face at court, it is obvious that the activists are trying to get a jury nullified and they should be charged.
It depends on whether the activist is handing out the literature to the actual jury or other people on the grounds. The first amendment is at play. I default to the freedom to express opinions. But, the jury process requires a measure of objectivity, which is not present if they are handed such literature.
I don't believe that activist should be charged with jury tempering for handing out nullification literature to them. I believe they should be let go with a warning. Jury is anyway not supposed to read that literature and they are aware of that. Also, probably court should prevent even the possibility of someone handing out anything on the courthouse grounds.
The intention of the checks and balances offered by the founding fathers was such that it empowered the individual citizens to be the last line of defense against tyranny. The current court model asks the jurors only to decide whether the law has been violated, but they are supposed to have the power to address the law itself. Jury nullification needs to be talked about more, not less!
