Public Comment

I don't like the way protesters are showing support for Michael Brown. The right to speak out and show disapproval of the grand jury's verdict is fine. But what connection is there between the grand jury's bad judgment and destruction of public buildings?  

What connection is there between the grand jury's bad judgment and destruction of commercial buildings? If people have a problem with the grand jury's unjust decision, why hurt those who are not directly involved and who did not harm the murdered teenaged boy? I don't understand the rationale for destroying property and hurting innocent citizens.
