A key piece of information to add insight.  Michael Strickland was badly beat up at a prior protest involving a progressive of sorts, and his assailant was I believe convicted of this assault.  
                                                                                                                              
This said we could really use some kind of preparatory mediation between groups representing libertarians as Michael, progressives, and others to bring an understanding of how we will conduct political demonstration going forward.   Pulling a gun really escalates a political confrontation.  And it isn't even in keeping with Michael's own wish to be a citizen journalist.
                                                                  
Our politicians such as Pres. Obama are really failing.  They pander to Black Lives Matter who berate the police into not even policing places like parts of Chicago.  Then, he asks to take guns from people needing to defend themselves. Ug
