I can see jury nullification as a valuable tool in situations where a direct approach will take a long time.  It's potentially a stopgap answer.

 

For example, I'm fairly certain that if clear heads could talk rationally, we'd probably not be classing pot as the serious drug it's filed as now.  However, doing so may take years, as nobody wants to admit the drugs won the drug war.  In that case, the best we can do is try and prevent lives from being damaged by the law one at a time-- IOW, nulling the law at the jury box.

 

Similarly, it might be the answer for the present, clearly stilted IP regime, cos while it's not reflective of most Americans' views, it is representative of a small segment which has a massive swing over the legislators.

 

Perhaps we need a new model for lawmaking.  Maybe random-draw for staffing the legislatures, one term only, so there's no campaign finance for problems.  For accountability, how about strapping them in an electric chair and giving them shocks proportional to their approval rating.
