lady, i cannot imagine what it would be like to have one's child on trial for murder, but standing outside the courthouse and "sending a warning to all men that this could happen to you" is pretty damned stupid.
yes, women are perfectly capable of violence, probably more than is admitted to in society, but men still commit the majority of crimes and are overwhelmingly the predators of children. how about the other 22 women your son was seeing in 2009 before his arrest? were all of them scheming Jezebels just waiting for a chance to falsely accuse him of kidnapping, rape and murder???
